Struct tokio::sync::SemaphorePermit[−][src]

#[must_use]pub struct SemaphorePermit<'a> { /* fields omitted */ }
[−]

A permit from the semaphore.

This type is created by the acquire method.

Implementations

impl<'a> SemaphorePermit<'a>[src][−]

pub fn forget(self)[src][−]

Forgets the permit without releasing it back to the semaphore. This can be used to reduce the amount of permits available from a semaphore.
