[−][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.
