Synchronous and Asynchronous Synchronization Primitives

WORK-IN-PROGRESS.

• THE CODE IS INCOMPLETE AND NOT AT ALL BATTLE-TESTED.

Low-level synchronization primitives that provide both synchronous and asynchronous interfaces.

Features

• Asynchronous counterparts of blocking and synchronous methods.
• Loom support: features = ["loom"].
• No spin-locks and no busy loops.

Lock

saa::Lock is a Low-level shared-exclusive lock that provides both synchronous and asynchronous interfaces. Synchronous locking methods such as lock_exclusive_sync or lock_shared_sync can be used with their asynchronous counterparts, lock_exclusive_async or lock_shared_async, at the same time. saa::Lock implements a heap-allocation-free fair wait queue that is shared among both synchronous and asynchronous methods.

Semaphore

saa::Semaphore is a synchronization primitive that allows a fixed number of threads to access a resource concurrently.
