This function is guaranteed to diverge (not return normally with a value), but depending on │ │ │ │ global configuration, it may either panic (resulting in unwinding or aborting as per │ │ │ │ configuration for all panics), or abort the process (with no unwinding).

  • │ │ │ │

    If the binary links against std (typically the case), then │ │ │ │ print a message to standard error and abort the process. │ │ │ │ This behavior can be replaced with set_alloc_error_hook and take_alloc_error_hook. │ │ │ │ Future versions of Rust may panic by default instead.

Expand description

Layout of a block of memory.

│ │ │ │

An instance of Layout describes a particular layout of memory. │ │ │ │ You build a Layout up as an input to give to an allocator.

│ │ │ │

All layouts have an associated size and a power-of-two alignment. The size, when rounded up to │ │ │ │ the nearest multiple of align, does not overflow isize (i.e., the rounded value will always be │ │ │ │ less than or equal to isize::MAX).

│ │ │ │

(Note that layouts are not required to have non-zero size, │ │ │ │ even though GlobalAlloc requires that all memory requests │ │ │ │ be non-zero in size. A caller must either ensure that conditions │ │ │ │ like this are met, use specific allocators with looser │ │ │ │ requirements, or use the more lenient Allocator interface.)

    A trait for borrowing data.

│ │ │ │  can be borrowed as str.

    impl<T, const N: usize> TryFrom<Box<[T]>> for Box<[T; N]>

    Source§

    fn try_from(boxed_slice: Box<[T]>) -> Result<Self, Self::Error>

    Attempts to convert a Box<[T]> into a Box<[T; N]>.

    │ │ │ │

    The conversion occurs in-place and does not require a │ │ │ │ new memory allocation.

    │ │ │ │
    §Errors
    │ │ │ │

    Returns the old Box<[T]> in the Err variant if │ │ │ │ boxed_slice.len() does not equal N.

    Source§

    fn try_from(vec: Vec<T>) -> Result<Self, Self::Error>

    Attempts to convert a Vec<T> into a Box<[T; N]>.

    │ │ │ │

    Like Vec::into_boxed_slice, this is in-place if vec.capacity() == N, │ │ │ │ but will require a reallocation otherwise.

    │ │ │ │
    §Errors
    │ │ │ │

    Returns the original Vec<T> in the Err variant if │ │ │ │ boxed_slice.len() does not equal N.

    │ │ │ │
    §Examples
    │ │ │ │

    This can be used with vec! to create an array on the heap:

    An ordered map based on a B-Tree.

    │ │ │ │

    B-Trees represent a fundamental compromise between cache-efficiency and actually minimizing │ │ │ │ the amount of work performed in a search. In theory, a binary search tree (BST) is the optimal │ │ │ │ choice for a sorted map, as a perfectly balanced BST performs the theoretical minimum amount of │ │ │ │ comparisons necessary to find an element (log2n). However, in practice the way this │ │ │ │ is done is very inefficient for modern computer architectures. In particular, every element │ │ │ │ is stored in its own individually heap-allocated node. This means that every single insertion │ │ │ │ triggers a heap-allocation, and every single comparison should be a cache-miss. Since these │ │ │ │ @@ -18,16 +18,16 @@ │ │ │ │

    Currently, our implementation simply performs naive linear search. This provides excellent │ │ │ │ performance on small nodes of elements which are cheap to compare. However in the future we │ │ │ │ would like to further explore choosing the optimal search strategy based on the choice of B, │ │ │ │ and possibly other factors. Using linear search, searching for a random element is expected │ │ │ │ to take B * log(n) comparisons, which is generally worse than a BST. In practice, │ │ │ │ however, performance is excellent.

    It is a logic error for a key to be modified in such a way that the key’s ordering relative to │ │ │ │ -any other key, as determined by the Ord trait, changes while it is in the map. This is │ │ │ │ -normally only possible through Cell, RefCell, global state, I/O, or unsafe code. │ │ │ │ +any other key, as determined by the Ord trait, changes while it is in the map. This is │ │ │ │ +normally only possible through Cell, RefCell, global state, I/O, or unsafe code. │ │ │ │ The behavior resulting from such a logic error is not specified, but will be encapsulated to the │ │ │ │ BTreeMap that observed the logic error and not result in undefined behavior. This could │ │ │ │ include panics, incorrect results, aborts, memory leaks, and non-termination.

    │ │ │ │

    Iterators obtained from functions such as BTreeMap::iter, BTreeMap::into_iter, BTreeMap::values, or │ │ │ │ BTreeMap::keys produce their items in order by key, and take worst-case logarithmic and │ │ │ │ amortized constant time per item returned.

    🔬This is a nightly-only experimental API. (btree_cursors #107540)
    Expand description

    A cursor over a BTreeMap.

    │ │ │ │

    A Cursor is like an iterator, except that it can freely seek back-and-forth.

    │ │ │ │

    Cursors always point to a gap between two elements in the map, and can │ │ │ │ operate on the two immediately adjacent elements.

    │ │ │ │

    A Cursor is created with the BTreeMap::lower_bound and BTreeMap::upper_bound methods.

    Expand description

    A cursor over a BTreeSet.

    │ │ │ │

    A Cursor is like an iterator, except that it can freely seek back-and-forth.

    │ │ │ │

    Cursors always point to a gap between two elements in the set, and can │ │ │ │ operate on the two immediately adjacent elements.

    │ │ │ │

    A Cursor is created with the BTreeSet::lower_bound and BTreeSet::upper_bound methods.

    A Cursor is like an iterator, except that it can freely seek back-and-forth.

    🔬This is a nightly-only experimental API. (vec_deque_iter_as_slices #123947)

    Views the underlying data as a pair of subslices of the original data.

    │ │ │ │

    The slices contain, in order, the contents of the deque not yet yielded │ │ │ │ by the iterator.

    │ │ │ │

    This has the same lifetime as the original VecDeque, and so the │ │ │ │ iterator can continue to be used while this exists.

    This type serves the purpose of being able to safely generate a │ │ │ │ C-compatible string from a Rust byte slice or vector. An instance of this │ │ │ │ type is a static guarantee that the underlying bytes contain no interior 0 │ │ │ │ bytes (“nul characters”) and that the final byte is 0 (“nul terminator”).

This is useful │ │ │ │ when you will be calling an extern function that takes a *const u8 argument which is not necessarily nul-terminated, plus another │ │ │ │ argument with the length of the string — like C’s strndup(). │ │ │ │ You can of course get the slice’s length with its │ │ │ │ -len method.

    If you need a &[u8] slice with the nul terminator, you │ │ │ │ can use CString::as_bytes_with_nul instead.

See the documentation for that function for a │ │ │ │ discussion on ensuring the lifetime of the raw pointer.

    A type representing an owned, C-compatible, nul-terminated string with no nul bytes in the │ │ │ │ middle.

    │ │ │ │

    This type serves the purpose of being able to safely generate a │ │ │ │ C-compatible string from a Rust byte slice or vector. An instance of this │ │ │ │ type is a static guarantee that the underlying bytes contain no interior 0 │ │ │ │ bytes (“nul characters”) and that the final byte is 0 (“nul terminator”).

    CString implements an as_ptr method through the Deref │ │ │ │ trait. This method will give you a *const c_char which you can │ │ │ │ feed directly to extern functions that expect a nul-terminated │ │ │ │ -string, like C’s strdup(). Notice that as_ptr returns a │ │ │ │ +string, like C’s strdup(). Notice that as_ptr returns a │ │ │ │ read-only pointer; if the C code writes to it, that causes │ │ │ │ undefined behavior.

    Alternatively, you can obtain a &[u8] slice from a │ │ │ │ CString with the CString::as_bytes method. Slices produced in this │ │ │ │ way do not contain the trailing nul terminator. This is useful │ │ │ │ when you will be calling an extern function that takes a *const u8 argument which is not necessarily nul-terminated, plus another │ │ │ │ argument with the length of the string — like C’s strndup(). │ │ │ │ You can of course get the slice’s length with its │ │ │ │ -len method.

    If you need a &[u8] slice with the nul terminator, you │ │ │ │ can use CString::as_bytes_with_nul instead.

    WARNING

    │ │ │ │

    The returned pointer is read-only; writing to it (including passing it │ │ │ │ to C code that writes to it) causes undefined behavior.

    │ │ │ │

    A Formatter represents various options related to formatting. Users do not │ │ │ │ construct Formatters directly; a mutable reference to one is passed to │ │ │ │ the fmt method of all formatting traits, like Debug and Display.

    │ │ │ │

    To interact with a Formatter, you’ll call various methods to change the │ │ │ │ various options related to formatting. For examples, please see the │ │ │ │ documentation of the methods defined on Formatter below.

    fn from_iter<I: IntoIterator<Item = T>>(iter: I) -> Self

    Takes each element in the Iterator and collects it into an Rc<[T]>.

    │ │ │ │
    §Performance characteristics
    §The general case
    │ │ │ │

    In the general case, collecting into Rc<[T]> is done by first │ │ │ │ collecting into a Vec<T>. That is, when writing the following:

    │ │ │ │ │ │ │ │ 
    let evens: Rc<[u8]> = (0..10).filter(|&x| x % 2 == 0).collect();
    │ │ │ │

    this behaves as if we wrote:

    │ │ │ │ │ │ │ │ @@ -901,103 +901,103 @@ │ │ │ │

    This will allocate as many times as needed for constructing the Vec<T> │ │ │ │ and then it will allocate once for turning the Vec<T> into the Rc<[T]>.

    │ │ │ │
    §Iterators of known length
    │ │ │ │

    When your Iterator implements TrustedLen and is of an exact size, │ │ │ │ a single allocation will be made for the Rc<[T]>. For example:

    │ │ │ │ │ │ │ │ 
    let evens: Rc<[u8]> = (0..10).collect(); // Just a single allocation happens here.

    A uniquely owned Rc.

    │ │ │ │

    This represents an Rc that is known to be uniquely owned – that is, have exactly one strong │ │ │ │ reference. Multiple weak pointers can be created, but attempts to upgrade those to strong │ │ │ │ references will fail unless the UniqueRc they point to has been converted into a regular Rc.

    │ │ │ │

    Because they are uniquely owned, the contents of a UniqueRc can be freely mutated. A common │ │ │ │ use case is to have an object be mutable during its initialization phase but then have it become │ │ │ │ immutable and converted to a normal Rc.

    │ │ │ │

    This can be used as a flexible way to create cyclic data structures, as in the example below.

    │ │ │ │

    An advantage of using UniqueRc over Rc::new_cyclic to build cyclic data structures is that │ │ │ │ -Rc::new_cyclic’s data_fn parameter cannot be async or return a Result. As shown in the │ │ │ │ +Rc::new_cyclic’s data_fn parameter cannot be async or return a Result. As shown in the │ │ │ │ previous example, UniqueRc allows for more flexibility in the construction of cyclic data, │ │ │ │ including fallible or async constructors.

    Weak is a version of Rc that holds a non-owning reference to the │ │ │ │ managed allocation.

    │ │ │ │

Thus it may return None │ │ │ │ +guarantees about the value still being present. Thus it may return None │ │ │ │ when upgraded. Note however that a Weak reference does prevent the allocation │ │ │ │ itself (the backing store) from being deallocated.

    │ │ │ │

    A Weak pointer is useful for keeping a temporary reference to the allocation │ │ │ │ managed by Rc without preventing its inner value from being dropped. It is also used to │ │ │ │ prevent circular references between Rc pointers, since mutual owning references │ │ │ │ would never allow either Rc to be dropped. For example, a tree could │ │ │ │ have strong Rc pointers from parent nodes to children, and Weak │ │ │ │ pointers from children back to their parents.

    │ │ │ │

    The typical way to obtain a Weak pointer is to call Rc::downgrade.

      data must be non-null, valid for both reads and writes for len * mem::size_of::<T>() many bytes, │ │ │ │ and it must be properly aligned. This means in particular:

      │ │ │ │
        │ │ │ │
      • The entire memory range of this slice must be contained within a single allocated object! │ │ │ │ Slices can never span across multiple allocated objects.
        • │ │ │ │
      • data must be non-null and aligned even for zero-length slices or slices of ZSTs. One │ │ │ │ reason for this is that enum layout optimizations may rely on references │ │ │ │ (including slices of any length) being aligned and non-null to distinguish │ │ │ │ them from other data. You can obtain a pointer that is usable as data │ │ │ │ -for zero-length slices using NonNull::dangling().

      │ │ │ │
      • │ │ │ │

      The memory referenced by the returned slice must not be accessed through any other pointer │ │ │ │ (not derived from the return value) for the duration of lifetime 'a. │ │ │ │ Both read and write accesses are forbidden.

    Function from_utf8

    1.36.0 (const: 1.63.0) · Source 
    pub const fn from_utf8(v: &[u8]) -> Result<&str, Utf8Error>
    Expand description

    Converts a slice of bytes to a string slice.

    │ │ │ │ +

    A string slice (&str) is made of bytes (u8), and a byte slice │ │ │ │ +(&[u8]) is made of bytes, so this function converts between │ │ │ │ +the two. Not all byte slices are valid string slices, however: &str requires │ │ │ │ that it is valid UTF-8. from_utf8() checks to ensure that the bytes are valid │ │ │ │ UTF-8, and then does the conversion.

    │ │ │ │

    If you are sure that the byte slice is valid UTF-8, and you don’t want to │ │ │ │ incur the overhead of the validity check, there is an unsafe version of │ │ │ │ this function, from_utf8_unchecked, which has the same │ │ │ │ behavior but skips the check.

    │ │ │ │

    If you need a String instead of a &str, consider │ │ │ │ String::from_utf8.

    │ │ │ │

    Because you can stack-allocate a [u8; N], and you can take a │ │ │ │ -&[u8] of it, this function is one way to have a │ │ │ │ +&[u8] of it, this function is one way to have a │ │ │ │ stack-allocated string. There is an example of this in the │ │ │ │ examples section below.

    │ │ │ │

    §Errors

    │ │ │ │

    Returns Err if the slice is not UTF-8 with a description as to why the │ │ │ │ provided slice is not UTF-8.

    A marker trait to express that a ReverseSearcher │ │ │ │ +can be used for a DoubleEndedIterator implementation.

    │ │ │ │

    For this, the impl of Searcher and ReverseSearcher need │ │ │ │ to follow these conditions:

    │ │ │ │
      │ │ │ │
    • All results of next() need to be identical │ │ │ │ to the results of next_back() in reverse order.
      • │ │ │ │
    • next() and next_back() need to behave as │ │ │ │ the two ends of a range of values, that is they │ │ │ │ can not “walk past each other”.
      • │ │ │ │
    │ │ │ │

    §Examples

    char::Searcher is a DoubleEndedSearcher because searching for a │ │ │ │ -char only requires looking at one at a time, which behaves the same │ │ │ │ +char only requires looking at one at a time, which behaves the same │ │ │ │ from both ends.

    (&str)::Searcher is not a DoubleEndedSearcher because │ │ │ │ the pattern "aa" in the haystack "aaa" matches as either │ │ │ │ "[aa]a" or "a[aa]", depending on which side it is searched.

    This method can help you truncate a string so that it’s still valid UTF-8, but doesn’t
│ │ │ │  exceed a given number of bytes. Note that this is done purely at the character level
│ │ │ │  and can still visually split graphemes, even though the underlying characters aren’t
│ │ │ │  split. For example, the emoji 🧑‍🔬 (scientist) could be split so that the string only
│ │ │ │  includes 🧑 (person) instead.

    impl Add<&str> for String
    Implements the + operator for concatenating two strings.
    
│ │ │ │  
    This consumes the String on the left-hand side and re-uses its buffer (growing it if
│ │ │ │  necessary). This is done to avoid allocating a new String and copying the entire contents on
│ │ │ │  every operation, which would lead to O(n^2) running time when building an n-byte string by
│ │ │ │  repeated concatenation.
    
│ │ │ │  
    The string on the right-hand side is only borrowed; its contents are copied into the returned
│ │ │ │  String.

    A thread-safe reference-counting pointer. ‘Arc’ stands for ‘Atomically

│ │ │ │  
    The type Arc<T> provides shared ownership of a value of type T,

│ │ │ │ +allocated in the heap. Invoking clone on Arc produces
│ │ │ │  a new Arc instance, which points to the same allocation on the heap as the
│ │ │ │  source Arc, while increasing a reference count. When the last Arc
│ │ │ │  pointer to a given allocation is destroyed, the value stored in that allocation (often
│ │ │ │  referred to as “inner value”) is also dropped.
    
│ │ │ │  
    Shared references in Rust disallow mutation by default, and Arc is no
│ │ │ │  exception: you cannot generally obtain a mutable reference to something
│ │ │ │  inside an Arc. If you need to mutate through an Arc, use

│ │ │ │  
    Note: This type is only available on platforms that support atomic
│ │ │ │  loads and stores of pointers, which includes all platforms that support
│ │ │ │  the std crate but not all those which only support alloc.
│ │ │ │  This may be detected at compile time using #[cfg(target_has_atomic = "ptr")].
    
│ │ │ │  
    §Thread Safety
    
│ │ │ │  
    Unlike Rc<T>, Arc<T> uses atomic operations for its reference
│ │ │ │  counting. This means that it is thread-safe. The disadvantage is that
│ │ │ │  atomic operations are more expensive than ordinary memory accesses. If you
│ │ │ │  are not sharing reference-counted allocations between threads, consider using
│ │ │ │  Rc<T> for lower overhead. Rc<T> is a safe default, because the
│ │ │ │  compiler will catch any attempt to send an Rc<T> between threads.
│ │ │ │  However, a library might choose Arc<T> in order to give library consumers
│ │ │ │  more flexibility.
    
│ │ │ │ -

    Arc<T> will implement Send and Sync as long as the T implements
│ │ │ │ +Send and Sync. Why can’t you put a non-thread-safe type T in an
│ │ │ │  Arc<T> to make it thread-safe? This may be a bit counter-intuitive at
│ │ │ │  first: after all, isn’t the point of Arc<T> thread safety? The key is
│ │ │ │  this: Arc<T> makes it thread safe to have multiple ownership of the same
│ │ │ │  data, but it  doesn’t add thread safety to its data. Consider
│ │ │ │ -Arc<RefCell<T>>. RefCell<T> isn’t Sync, and if Arc<T> was always
│ │ │ │ -Send, Arc<RefCell<T>> would be as well. But then we’d have a problem:
│ │ │ │ -RefCell<T> is not thread safe; it keeps track of the borrowing count using
│ │ │ │ +Arc<RefCell<T>>. RefCell<T> isn’t Sync, and if Arc<T> was always

│ │ │ │ +RefCell<T> is not thread safe; it keeps track of the borrowing count using
│ │ │ │  non-atomic operations.
    
│ │ │ │  
    In the end, this means that you may need to pair Arc<T> with some sort of
│ │ │ │  std::sync type, usually Mutex<T>.
    
│ │ │ │  
    §Breaking cycles with Weak
    
│ │ │ │  
    The downgrade method can be used to create a non-owning
│ │ │ │  Weak pointer. A Weak pointer can be upgraded
│ │ │ │ -to an Arc, but this will return None if the value stored in the allocation has

│ │ │ │  inside the allocation alive; however, they do keep the allocation
│ │ │ │  (the backing store for the value) alive.
    
│ │ │ │  
    A cycle between Arc pointers will never be deallocated. For this reason,
│ │ │ │  Weak is used to break cycles. For example, a tree could have
│ │ │ │  strong Arc pointers from parent nodes to children, and Weak
│ │ │ │  pointers from children back to their parents.

    impl<T> From<T> for Arc<T>
    Source§
    fn from(t: T) -> Self
    Converts a T into an Arc<T>
    
│ │ │ │  
    The conversion moves the value into a
│ │ │ │  newly allocated Arc. It is equivalent to
│ │ │ │  calling Arc::new(t).
    
│ │ │ │  
    §Example
    
│ │ │ │  
    let x = 5;
│ │ │ │  let arc = Arc::new(5);
│ │ │ │  
│ │ │ │  assert_eq!(Arc::from(x), arc);

    fn from_iter<I: IntoIterator<Item = T>>(iter: I) -> Self
    Takes each element in the Iterator and collects it into an Arc<[T]>.
    
│ │ │ │  
    §Performance characteristics
    §The general case
    
│ │ │ │  
    In the general case, collecting into Arc<[T]> is done by first
│ │ │ │  collecting into a Vec<T>. That is, when writing the following:
    
│ │ │ │  
│ │ │ │  
    let evens: Arc<[u8]> = (0..10).filter(|&x| x % 2 == 0).collect();
    
│ │ │ │  
    this behaves as if we wrote:
    
│ │ │ │  
│ │ │ │ @@ -1110,103 +1110,103 @@
│ │ │ │  
    This will allocate as many times as needed for constructing the Vec<T>
│ │ │ │  and then it will allocate once for turning the Vec<T> into the Arc<[T]>.
    
│ │ │ │  
    §Iterators of known length
    
│ │ │ │  
    When your Iterator implements TrustedLen and is of an exact size,
│ │ │ │  a single allocation will be made for the Arc<[T]>. For example:
    
│ │ │ │  
│ │ │ │  
    let evens: Arc<[u8]> = (0..10).collect(); // Just a single allocation happens here.

    Weak is a version of Arc that holds a non-owning reference to the
│ │ │ │  managed allocation.
    
│ │ │ │  
    The allocation is accessed by calling upgrade on the Weak
│ │ │ │ -pointer, which returns an Option<Arc<T>>.
    
│ │ │ │ +pointer, which returns an Option<Arc<T>>.
    
│ │ │ │

│ │ │ │  prevent the value stored in the allocation from being dropped, and Weak itself makes no
│ │ │ │ -guarantees about the value still being present. Thus it may return None
│ │ │ │ +guarantees about the value still being present. Thus it may return None
│ │ │ │  when upgraded. Note however that a Weak reference does prevent the allocation
│ │ │ │  itself (the backing store) from being deallocated.
    
│ │ │ │  
    A Weak pointer is useful for keeping a temporary reference to the allocation
│ │ │ │  managed by Arc without preventing its inner value from being dropped. It is also used to
│ │ │ │  prevent circular references between Arc pointers, since mutual owning references
│ │ │ │  would never allow either Arc to be dropped. For example, a tree could
│ │ │ │  have strong Arc pointers from parent nodes to children, and Weak
│ │ │ │  pointers from children back to their parents.
    
│ │ │ │  
    The typical way to obtain a Weak pointer is to call Arc::downgrade.

│ │ │ │  Bergdoll, which combines the fast average case of randomized quicksort with the fast worst
│ │ │ │  case of heapsort, while achieving linear time on fully sorted and reversed inputs. And
│ │ │ │  O(k * log(n)) where k is the number of distinct elements in the input. It leverages
│ │ │ │  superscalar out-of-order execution capabilities commonly found in CPUs, to efficiently
│ │ │ │  perform the operation.
      
│ │ │ │  
      In the worst case, the algorithm allocates temporary storage in a Vec<(K, usize)> the
│ │ │ │  length of the slice.
      
│ │ │ │  
      §Panics
      
│ │ │ │ -
      May panic if the implementation of Ord for K does not implement a total order, or if
│ │ │ │ -the Ord implementation panics.
      
│ │ │ │ +
      May panic if the implementation of Ord for K does not implement a total order, or if
│ │ │ │ +the Ord implementation panics.
      
│ │ │ │  
      All safe functions on slices preserve the invariant that even if the function panics, all
│ │ │ │  original elements will remain in the slice and any possible modifications via interior
│ │ │ │  mutability are observed in the input. This ensures that recovery code (for instance inside
│ │ │ │  of a Drop or following a catch_unwind) will still have access to all the original
│ │ │ │  elements. For instance, if the slice belongs to a Vec, the Vec::drop method will be able
│ │ │ │  to dispose of all contained elements.
      
│ │ │ │  
      §Examples
      
│ │ │ │  
      let mut v = [4i32, -5, 1, -3, 2, 10];
│ │ │ │  
│ │ │ │  // Strings are sorted by lexicographical order.
│ │ │ │  v.sort_by_cached_key(|k| k.to_string());
│ │ │ │  assert_eq!(v, [-3, -5, 1, 10, 2, 4]);

      §Current implementation
      
│ │ │ │  
      The current implementation is based on ipnsort by Lukas Bergdoll and Orson Peters, which
│ │ │ │  combines the fast average case of quicksort with the fast worst case of heapsort, achieving
│ │ │ │  linear time on fully sorted and reversed inputs. On inputs with k distinct elements, the
│ │ │ │  expected time to sort the data is O(n * log(k)).
      
│ │ │ │  
      It is typically faster than stable sorting, except in a few special cases, e.g., when the
│ │ │ │  slice is partially sorted.

      Here is an example which increments every integer in a vector,\nchecking for overflow:
      \n\n
      let v = vec![1, 2];\nlet res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32|\n    x.checked_add(1).ok_or(\"Overflow!\")\n).collect();\nassert_eq!(res, Ok(vec![2, 3]));
      \n
      Here is another example that tries to subtract one from another list\nof integers, this time checking for underflow:
      \n\n
      let v = vec![1, 2, 0];\nlet res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32|\n    x.checked_sub(1).ok_or(\"Underflow!\")\n).collect();\nassert_eq!(res, Err(\"Underflow!\"));
      \n
      Here is a variation on the previous example, showing that no\nfurther elements are taken from iter after the first Err.
      \n\n
      let v = vec![3, 2, 1, 10];\nlet mut shared = 0;\nlet res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32| {\n    shared += x;\n    x.checked_sub(2).ok_or(\"Underflow!\")\n}).collect();\nassert_eq!(res, Err(\"Underflow!\"));\nassert_eq!(shared, 6);
      \n
      Since the third element caused an underflow, no further elements were taken,\nso the final value of shared is 6 (= 3 + 2 + 1), not 16.

      where\n    E: Debug,
      Returns the contained Ok value, consuming the self value.
      \n
      Because this function may panic, its use is generally discouraged.\nInstead, prefer to use pattern matching and handle the Err\ncase explicitly, or call unwrap_or, unwrap_or_else, or\nunwrap_or_default.
      \n
      §Panics
      \n
      Panics if the value is an Err, with a panic message including the\npassed message, and the content of the Err.
      \n
      §Examples
      \n
      ⓘ
      let x: Result<u32, &str> = Err(\"emergency failure\");\nx.expect(\"Testing expect\"); // panics with `Testing expect: emergency failure`
      \n
      §Recommended Message Style
      \n
      We recommend that expect messages are used to describe the reason you\nexpect the Result should be Ok.
      \n\n
      ⓘ
      let path = std::env::var(\"IMPORTANT_PATH\")\n    .expect(\"env variable `IMPORTANT_PATH` should be set by `wrapper_script.sh`\");
      \n
      Hint: If you’re having trouble remembering how to phrase expect\nerror messages remember to focus on the word “should” as in “env\nvariable should be set by blah” or “the given binary should be available\nand executable by the current user”.
      \n
      For more detail on expect message styles and the reasoning behind our recommendation please\nrefer to the section on “Common Message\nStyles” in the\nstd::error module docs.

      Here is an example which increments every integer in a vector,\nchecking for overflow:
      \n\n
      let v = vec![1, 2];\nlet res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32|\n    x.checked_add(1).ok_or(\"Overflow!\")\n).collect();\nassert_eq!(res, Ok(vec![2, 3]));
      \n
      Here is another example that tries to subtract one from another list\nof integers, this time checking for underflow:
      \n\n
      let v = vec![1, 2, 0];\nlet res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32|\n    x.checked_sub(1).ok_or(\"Underflow!\")\n).collect();\nassert_eq!(res, Err(\"Underflow!\"));
      \n
      Here is a variation on the previous example, showing that no\nfurther elements are taken from iter after the first Err.
      \n\n
      let v = vec![3, 2, 1, 10];\nlet mut shared = 0;\nlet res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32| {\n    shared += x;\n    x.checked_sub(2).ok_or(\"Underflow!\")\n}).collect();\nassert_eq!(res, Err(\"Underflow!\"));\nassert_eq!(shared, 6);
      \n
      Since the third element caused an underflow, no further elements were taken,\nso the final value of shared is 6 (= 3 + 2 + 1), not 16.

      pub fn expect(self, msg: &str) -> T
      where\n    E: Debug,
      Returns the contained Ok value, consuming the self value.
      \n
      Because this function may panic, its use is generally discouraged.\nInstead, prefer to use pattern matching and handle the Err\ncase explicitly, or call unwrap_or, unwrap_or_else, or\nunwrap_or_default.
      \n
      §Panics
      \n
      Panics if the value is an Err, with a panic message including the\npassed message, and the content of the Err.
      \n
      §Examples
      \n
      ⓘ
      let x: Result<u32, &str> = Err(\"emergency failure\");\nx.expect(\"Testing expect\"); // panics with `Testing expect: emergency failure`
      \n
      §Recommended Message Style
      \n
      We recommend that expect messages are used to describe the reason you\nexpect the Result should be Ok.
      \n\n
      ⓘ
      let path = std::env::var(\"IMPORTANT_PATH\")\n    .expect(\"env variable `IMPORTANT_PATH` should be set by `wrapper_script.sh`\");
      \n
      Hint: If you’re having trouble remembering how to phrase expect\nerror messages remember to focus on the word “should” as in “env\nvariable should be set by blah” or “the given binary should be available\nand executable by the current user”.
      \n
      For more detail on expect message styles and the reasoning behind our recommendation please\nrefer to the section on “Common Message\nStyles” in the\nstd::error module docs.

      pub fn unwrap(self) -> T
      where\n    E: Debug,
      Returns the contained Ok value, consuming the self value.
      \n
      Because this function may panic, its use is generally discouraged.\nPanics are meant for unrecoverable errors, and\nmay abort the entire program.
      \n
      Instead, prefer to use the ? (try) operator, or pattern matching\nto handle the Err case explicitly, or call unwrap_or,\nunwrap_or_else, or unwrap_or_default.
      \n
      §Panics
      \n
      Panics if the value is an Err, with a panic message provided by the\nErr’s value.
      \n
      §Examples
      \n
      Basic usage:
      \n\n

      ⓘ

      Consumes the self argument then, if Ok, returns the contained\nvalue, otherwise if Err, returns the default value for that\ntype.
      \n
      §Examples
      \n
      Converts a string to an integer, turning poorly-formed strings\ninto 0 (the default value for integers). parse converts\na string to any other type that implements FromStr, returning an\nErr on error.
      \n\n
