std::slice::IterMut - Rust (original) (raw)

pub fn [into_slice](#method.into%5Fslice)(self) -> [&'a mut [T]](../primitive.slice.html)

1.4.0

[src]

View the underlying data as a subslice of the original data.

To avoid creating &mut references that alias, this is forced to consume the iterator. Consider using the Slice andSliceMut implementations for obtaining slices with more restricted lifetimes that do not consume the iterator.

Basic usage:

let mut slice = &mut [1, 2, 3];

{

let mut iter = slice.iter_mut();

iter.next();

println!("{:?}", iter.into_slice());

}

{

let mut iter = slice.iter_mut();

*iter.next().unwrap() += 1;

}

println!("{:?}", slice);Run
