Trait implemented by a collection types which need to support collection confinement.

Required Associated Types

type Item

Item type contained within the collection.

Required Methods

fn with_capacity(capacity: usize) -> Self

Creates new collection with certain capacity.

fn len(&self) -> usize

Returns the length of a collection.

fn push(&mut self, elem: Self::Item)

Pushes or inserts an element to the collection.

fn clear(&mut self)

Removes all elements from the collection.

Provided Methods

fn is_empty(&self) -> bool

Detects whether collection is empty.

Object Safety

This trait is not object safe.
