[−][src]Struct tokio_sync::semaphore::Semaphore
Futures-aware semaphore.
Methods
impl Semaphore[src][−]
pub fn new(permits: usize) -> Semaphore[src][−]
pub fn available_permits(&self) -> usize[src][−]
Returns the current number of available permits
pub fn close(&self)[src][−]
Close the semaphore. This prevents the semaphore from issuing new permits and notifies all pending waiters.
pub fn add_permits(&self, n: usize)[src][−]
Add n new permits to the semaphore.
