Struct PeekMut 

pub struct PeekMut<'a, T, A = Global>
where
    A: Allocator,
{ /* private fields */ }

🔬This is a nightly-only experimental API. (vec_peek_mut #122742)

Structure wrapping a mutable reference to the last item in a Vec.

This struct is created by the peek_mut method on Vec. See its documentation for more.

Implementations

impl<'a, T, A> PeekMut<'a, T, A>

where A: Allocator,

pub fn pop(this: PeekMut<'a, T, A>) -> T

🔬This is a nightly-only experimental API. (vec_peek_mut #122742)

Removes the peeked value from the vector and returns it.
