Description: API documentation for the Rust `IntoIter` struct in crate `collections`.
Keywords: rust, rustlang, rust-lang, IntoIter

# Struct collections::vec::IntoIter 1.0.0 [−] [src]

    pub struct IntoIter<T> { /* fields omitted */ }

An iterator that moves out of a vector.

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

## Methods

### `impl<T> IntoIter<T>`
[src]

#### `fn as_slice(&self) -> &[T]`
1.15.0

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(&mut self) -> &mut [T]`
1.15.0

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');

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
