pub trait BorrowMut<Borrowed>: Borrow<Borrowed> where
Borrowed: ?Sized, {
fn borrow_mut(&mut self) -> &mut Borrowed;
}
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.
fn borrow_mut(&mut self) -> &mut Borrowed
Mutably borrows from an owned value.
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);
