pub struct Shared<Fut> where
    Fut: Future,  { /* private fields */ }

Expand description

Future for the shared method.

Implementations

source

impl<Fut> Shared<Fut> where
Fut: Future,
<Fut as Future>::Output: Clone,

source

pub fn peek(&self) -> Option<&<Fut as Future>::Output>

Returns Some containing a reference to this Shared’s output if it has already been computed by a clone or None if it hasn’t been computed yet or this Shared already returned its output from poll.

source

pub fn downgrade(&self) -> Option<WeakShared<Fut>>

Creates a new WeakShared for this Shared.

Returns None if it has already been polled to completion.

source

pub fn strong_count(&self) -> Option<usize>

Gets the number of strong pointers to this allocation.

Returns None if it has already been polled to completion.

Safety

This method by itself is safe, but using it correctly requires extra care. Another thread can change the strong count at any time, including potentially between calling this method and acting on the result.

source

pub fn weak_count(&self) -> Option<usize>

Gets the number of weak pointers to this allocation.

Returns None if it has already been polled to completion.

Safety

This method by itself is safe, but using it correctly requires extra care. Another thread can change the weak count at any time, including potentially between calling this method and acting on the result.
