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>

source

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.
