Struct futures::prelude::future::WeakShared[−][src]

pub struct WeakShared<Fut>(_)
 where
    Fut: Future;

A weak reference to a Shared that can be upgraded much like an Arc.

Implementations

`impl<Fut> WeakShared<Fut> where Fut: Future,` [src]

`pub fn upgrade(&self) -> Option<Shared<Fut>>`[src]

Attempts to upgrade this WeakShared into a Shared.

Returns None if all clones of the Shared have been dropped or polled to completion.
