Crate futures_locks

A library of Futures-aware locking primitives. These locks can safely be used in asynchronous environments like Tokio. When they block, they'll only block a single task, not the entire reactor.

These primitives generally work much like their counterparts from the standard library. But instead of blocking, they return a Future that completes when the lock has been acquired.

Examples

let mtx = Mutex::<u32>::new(0);
let fut = mtx.lock().map(|mut guard| { *guard += 5; });
spawn(fut).wait_future();
assert_eq!(mtx.try_unwrap().unwrap(), 5);

Structs

Mutex	A Futures-aware Mutex.
MutexFut	A Future representing a pending Mutex acquisition.
MutexGuard	An RAII mutex guard, much like std::sync::MutexGuard. The wrapped data can be accessed via its Deref and DerefMut implementations.
MutexWeak	MutexWeak is a non-owning reference to a Mutex. MutexWeak is to Mutex as std::sync::Weak is to std::sync::Arc.
RwLock	A Futures-aware RwLock.
RwLockReadFut	A Future representing a pending RwLock shared acquisition.
RwLockReadGuard	An RAII guard, much like std::sync::RwLockReadGuard. The wrapped data can be accessed via its Deref implementation.
RwLockWriteFut	A Future representing a pending RwLock exclusive acquisition.
RwLockWriteGuard	An RAII guard, much like std::sync::RwLockWriteGuard. The wrapped data can be accessed via its Deref and DerefMut implementations.
