Struct futures_intrusive::sync::GenericSharedSemaphoreReleaser

source · [−]

pub struct GenericSharedSemaphoreReleaser<MutexType: RawMutex> { /* private fields */ }

Expand description

An RAII guard returned by the acquire and try_acquire methods.

When this structure is dropped (falls out of scope), the amount of permits that was used in the acquire() call will be released back to the Semaphore.

Implementations

source

impl<MutexType: RawMutex> GenericSharedSemaphoreReleaser<MutexType>

source

pub fn disarm(&mut self) -> usize

Prevents the SharedSemaphoreReleaser from automatically releasing the permits when it gets dropped.

This is helpful if the permits must be acquired for a longer lifetime than the one of the SemaphoreReleaser.

If this method is used it is important to release the acquired permits manually back to the Semaphore.
