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

NewCond returns a new Cond with Locker l.

OnceFunc returns a function that invokes f only once.

OnceValue returns a function that invokes f only once and returns the value returned by f.

OnceValues returns a function that invokes f only once and returns the values returned by f.

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

Map is like a Go map[any]any but is safe for concurrent use by multiple goroutines without additional locking or coordination.

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.

A RWMutex is a reader/writer mutual exclusion lock.

A WaitGroup waits for a collection of goroutines to finish.

A Locker represents an object that can be locked and unlocked.
