Struct futures_intrusive::sync::GenericSemaphoreReleaser

pub struct GenericSemaphoreReleaser<'a, MutexType: RawMutex> { /* private fields */ }

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

impl<MutexType: RawMutex> GenericSemaphoreReleaser<'_, MutexType>

pub fn disarm(&mut self) -> usize

Prevents the SemaphoreReleaser 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.
