Trait Push 

pub trait Push {
    type Item;
    type ItemView<'a>
       where Self: 'a;

    // Required method
    fn push<'a>(&'a mut self, item: Self::Item) -> Self::ItemView<'a>;
}

Abstracts something which can push Item into self

Required Associated Types

type Item

Item stocked in the collection

type ItemView<'a> where Self: 'a

Represent a way to access Item in the collection directly after push

Required Methods

fn push<'a>(&'a mut self, item: Self::Item) -> Self::ItemView<'a>

push an item into a collection, no guarantee on ordering.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
