pub struct OnceQueue<T: Identify> { /* private fields */ }

Implementations

impl<T: Identify> OnceQueue<T>

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn reset(&mut self)

Clears the queue itself and insertion history.

pub fn iter(&self) -> Iter<'_, T>

pub fn is_pushable(&self, value: &T) -> bool

pub fn count(&self, value: &T) -> u32

pub fn push_back(&mut self, value: T) -> Result<(), T>

Appends the value at the end of the queue if the queue has not seen the value before.

If the queue has seen the value, then returns it within error.

pub fn push_front(&mut self, value: T) -> Result<(), T>

Appends the value at the beginning of the queue if the queue has not seen the value before.

If the queue has seen the value, then returns it within error.

pub fn push_back_force(&mut self, value: T)

Appends the value at the end of the queue regardless of whether the queue has seen the value before.

pub fn push_front_force(&mut self, value: T)

Appends the value at the beginning of the queue regardless of whether the queue has seen the value before.

pub fn pop_back(&mut self) -> Option<T>

Removes the last value, then returns it.

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

Removes the first value, then returns it.
