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
