Trait Queue

pub trait Queue<T> {
    // Required methods
    fn with_capacity(capacity: usize) -> Self;
    fn len(&self) -> usize;
    fn push_back(&mut self, val: T);
    fn pop_front(&mut self) -> Option<T>;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

Required Methods

fn with_capacity(capacity: usize) -> Self

fn len(&self) -> usize

fn push_back(&mut self, val: T)

fn pop_front(&mut self) -> Option<T>

Provided Methods

fn is_empty(&self) -> bool

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.
