Package atomic provides low-level atomic memory primitives useful for implementing synchronization algorithms.

Cond implements a condition variable, a rendezvous point for goroutines waiting for or announcing the occurrence of an event.

A Mutex is a mutual exclusion lock.

Once is an object that will perform exactly one action.

A Pool is a set of temporary objects that may be individually saved and retrieved.

An RWMutex is a reader/writer mutual exclusion lock.
