Trait PrioDeque 

pub trait PrioDeque: PrioQueue + Deque {
    // Provided methods
    fn push_pop_back(&mut self, item: Self::Item) -> Self::Item
       where Self: AddRemove { ... }
    fn replace_back(&mut self, item: Self::Item) -> Option<Self::Item>
       where Self: AddRemove { ... }
}

A double-ended priority queue.

Provided Methods

fn push_pop_back(&mut self, item: Self::Item) -> Self::Item

where Self: AddRemove,

Pushes the given item onto the deque, then removes the item at the back of the deque and returns it.

This method may be deprecated in favor of back_mut in the future.

fn replace_back(&mut self, item: Self::Item) -> Option<Self::Item>

where Self: AddRemove,

Removes the item at the back of the deque, then pushes the given item onto the deque.

Returns the item that was removed, or None if the deque was empty.

This method may be deprecated in favor of back_mut in the future.

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.
