Struct tokio::sync::SemaphorePermit
source · pub struct SemaphorePermit<'a> { /* private fields */ }
Expand description
A permit from the semaphore.
This type is created by the acquire
method.
Implementations§
source§impl<'a> SemaphorePermit<'a>
impl<'a> SemaphorePermit<'a>
sourcepub fn forget(self)
pub fn forget(self)
Forgets the permit without releasing it back to the semaphore. This can be used to reduce the amount of permits available from a semaphore.
sourcepub fn merge(&mut self, other: Self)
pub fn merge(&mut self, other: Self)
Merge two SemaphorePermit
instances together, consuming other
without releasing the permits it holds.
Permits held by both self
and other
are released when self
drops.
Panics
This function panics if permits from different Semaphore
instances
are merged.
