Struct `IntoIter`

struct IntoIter<T, A: Allocator = crate::alloc::Global> { ... }

An iterator that moves out of a vector.

This struct is created by the into_iter method on Vec (provided by the IntoIterator trait).

Example

let v = vec![0, 1, 2];
let iter: std::vec::IntoIter<_> = v.into_iter();

Implementations

`impl<T, A: Allocator> IntoIter<T, A>`

fn as_slice(self: &Self) -> &[T]

Returns the remaining items of this iterator as a slice.

Examples

let vec = vec!['a', 'b', 'c'];
let mut into_iter = vec.into_iter();
assert_eq!(into_iter.as_slice(), &['a', 'b', 'c']);
let _ = into_iter.next().unwrap();
assert_eq!(into_iter.as_slice(), &['b', 'c']);

fn as_mut_slice(self: &mut Self) -> &mut [T]

Returns the remaining items of this iterator as a mutable slice.

Examples

let vec = vec!['a', 'b', 'c'];
let mut into_iter = vec.into_iter();
assert_eq!(into_iter.as_slice(), &['a', 'b', 'c']);
into_iter.as_mut_slice()[2] = 'z';
assert_eq!(into_iter.next().unwrap(), 'a');
assert_eq!(into_iter.next().unwrap(), 'b');
assert_eq!(into_iter.next().unwrap(), 'z');

fn allocator(self: &Self) -> &A

Returns a reference to the underlying allocator.
