Trait len_trait::LenMut

pub trait LenMut: Default + LenZero {
    fn truncate(&mut self, len: usize);
}

A collection with a "mutable" length, i.e. a truncatable collection.

Truncating the collection must take O(1) time and space after all of the removed elements in the collection are dropped.

Required Methods

fn truncate(&mut self, len: usize)

Truncates the collection so that it is no greater than len long.
