Types

type T

type T chan semaphore

func New

func New(limit int) T

New creates a new semaphore of a given capacity.

func (T) Acquire

func (t T) Acquire()

Acquire causes threads waiting on release to stop working. Note that because the channel is buffered, this can execute as many times as number of buffers, thus blocking subsequent callers until one of the buffers is released

func (T) Release

func (t T) Release() T

Release can be waited on or selected to get a stop work signal. This essentially empties a slot in the semaphore which allows another thread to acquire it
