Struct PeekMut

Source

pub struct PeekMut<'a, T> { /* private fields */ }

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

Expand description

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.
