pub struct Exact<K: Key, P: Copy + Ord> { /* private fields */ }

Specialized one-action book with the minimum resident footprint.

Implementations

impl<K: Key, P: Copy + Ord> Exact<K, P>

pub fn try_new(capacity: Count) -> Result<Self, Error>

Trait Implementations

impl<K: Key, P: Copy + Ord> Book<K, P> for Exact<K, P>

fn schedule(&mut self, key: K, item: Scheduled<P>) -> Result<(), Error<K>>

fn cancel(&mut self, key: K) -> Mutation

fn cancel_one(&mut self, key: K, action: Action) -> Mutation

fn peek(&self) -> Option<(K, Scheduled<P>)>

fn poll_due(&mut self, now: P) -> Poll<Expired<K, P>>

fn len(&self) -> usize

fn pop_due(&mut self, now: P) -> Option<Expired<K, P, W>>

Drains lazy renewals until an expiry or an idle book is reached. This may visit every resident entry; event-loop turns use poll_due to bound renewal work before yielding to other connections.
