Struct Access

pub struct Access<'a, T> { /* private fields */ }

A Future of a queued access to the inner item.

This can be constructed from AccessQueue::access. It is a Future, and it resolves to an AccessGuard, which dereferences to the inner item guarded by the access queue.

Implementations

impl<'a, T> Access<'a, T>

pub fn skip_queue(&self) -> &T

Access the guarded item without waiting in the AccessQueue.

This can be used to access the item without following the limitations on the number of allowed concurrent accesses.

Trait Implementations

impl<'a, T: Debug> Debug for Access<'a, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T> Future for Access<'a, T>

type Output = AccessGuard<'a, T>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, ctx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
