Struct Last 

pub struct Last;

🔬This is a nightly-only experimental API. (sliceindex_wrappers)

Always accesses the last element of the slice.

Examples

#![feature(sliceindex_wrappers)]
#![feature(slice_index_methods)]

use core::index::Last;
use core::slice::SliceIndex;

let s = &[0, 1, 2, 3];

assert_eq!(&3, &s[Last]);
assert_eq!(None, Last.get(&[] as &[usize]));

Trait Implementations

impl Debug for Last

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> SliceIndex<[T]> for Last

type Output = T

The output type returned by methods.

fn get(self, slice: &[T]) -> Option<&<Last as SliceIndex<[T]>>::Output>

🔬This is a nightly-only experimental API. (slice_index_methods)

Returns a shared reference to the output at this location, if in bounds.

fn get_mut( self, slice: &mut [T], ) -> Option<&mut <Last as SliceIndex<[T]>>::Output>

🔬This is a nightly-only experimental API. (slice_index_methods)

Returns a mutable reference to the output at this location, if in bounds.

unsafe fn get_unchecked( self, slice: *const [T], ) -> *const <Last as SliceIndex<[T]>>::Output

🔬This is a nightly-only experimental API. (slice_index_methods)

Returns a pointer to the output at this location, without performing any bounds checking.

unsafe fn get_unchecked_mut( self, slice: *mut [T], ) -> *mut <Last as SliceIndex<[T]>>::Output

🔬This is a nightly-only experimental API. (slice_index_methods)

Returns a mutable pointer to the output at this location, without performing any bounds checking.

fn index(self, slice: &[T]) -> &<Last as SliceIndex<[T]>>::Output

🔬This is a nightly-only experimental API. (slice_index_methods)

Returns a shared reference to the output at this location, panicking if out of bounds.

fn index_mut(self, slice: &mut [T]) -> &mut <Last as SliceIndex<[T]>>::Output

🔬This is a nightly-only experimental API. (slice_index_methods)

Returns a mutable reference to the output at this location, panicking if out of bounds.
