Struct SemaphoreGuard

Source 
pub struct SemaphoreGuard<T> { /* private fields */ }
Expand description

RAII guard used to release access to the semaphore automatically when it falls out of scope.

Returned from Semaphore::try_access.

§Sharing guards

There are cases where, once acquired, you want to share a guard between multiple threads of execution. This pattern can be implemented by wrapping the acquired guard into an Rc or Arc reference.
