Trait concurrency_traits::semaphore::TrySemaphore

pub unsafe trait TrySemaphore: Default {
    fn try_wait(&self) -> bool;
    fn signal(&self);
}

A generic semaphore that has try operations.

Safety

This trait is marked as unsafe to allow for safe code to rely on the standard semaphore contract. Default implementations should initialize the count at 0.

Required methods

fn try_wait(&self) -> bool

Returns true if can decrement and did, or false if cannot.

fn signal(&self)

Increments the counter.
