Struct `WeakShared`

struct WeakShared<Fut: Future>(_)

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

Implementations

`impl<Fut: Future> WeakShared<Fut>`

fn upgrade(self: &Self) -> Option<Shared<Fut>>

Attempts to upgrade this WeakShared into a Shared.

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