Struct PeekMut 

pub struct PeekMut<'a, T, A: Allocator = Global> {
    vec: &'a mut Vec<T, A>,
}

🔬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.
