Struct holochain::prelude::dependencies::kitsune_p2p_types::dependencies::futures::prelude::future::Shared
pub struct Shared<Fut>where
Fut: Future,{ /* private fields */ }
Expand description
Future for the shared
method.
Implementations
pub fn downgrade(&self) -> Option<WeakShared<Fut>>
pub fn downgrade(&self) -> Option<WeakShared<Fut>>
Creates a new WeakShared
for this Shared
.
Returns None
if it has already been polled to completion.
pub fn strong_count(&self) -> Option<usize>
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.
