pub trait BorrowMut<Borrowed>: Borrow<Borrowed>
where Borrowed: ?Sized,
{ // Required method fn borrow_mut(&mut self) -> &mut Borrowed; }
Expand description

A trait for mutably borrowing data.

As a companion to Borrow<T> this trait allows a type to borrow as an underlying type by providing a mutable reference. See Borrow<T> for more information on borrowing as another type.

Required Methods§

fn borrow_mut(&mut self) -> &mut Borrowed

Mutably borrows from an owned value.

§Examples
use std::borrow::BorrowMut;

fn check<T: BorrowMut<[i32]>>(mut v: T) {
    assert_eq!(&mut [1, 2, 3], v.borrow_mut());
}

let v = vec![1, 2, 3];

check(v);
