Struct Acquire 

pub struct Acquire<'a> { /* private fields */ }

The wait for permits of Semaphore::acquire and Semaphore::acquire_many.

Cancel safe: dropping it gives up its place in line; if its permits were already granted, they go back and the next waiter is served.

Trait Implementations

impl Debug for Acquire<'_>

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

Formats the value using the given formatter.

impl Drop for Acquire<'_>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<'a> Future for Acquire<'a>

type Output = Result<SemaphorePermit<'a>, AcquireError>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &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.
