Struct futures::future::Shared [−][src]
#[must_use = "futures do nothing unless polled"]pub struct Shared<Fut> where
Fut: Future, { /* fields omitted */ }
A future that is cloneable and can be polled in multiple threads.
Use Future::shared() method to convert any future into a Shared future.
Methods
impl<Fut> Shared<Fut> where
Fut: Future, [src]
impl<Fut> Shared<Fut> where
Fut: Future, pub fn peek(&self) -> Option<Arc<<Fut as Future>::Output>>[src]
pub fn peek(&self) -> Option<Arc<<Fut as Future>::Output>>If any clone of this Shared has completed execution, returns its result immediately
without blocking. Otherwise, returns None without triggering the work represented by
this Shared.
