Types

type Mutex

type Mutex struct {
	// contains filtered or unexported fields
}

Mutex is a struct that keeps track of a set of mutexes with a given ID. It can be used for making sure only one goroutine gets given the mutex per ID.

func NewMutex

func NewMutex() *Mutex

NewMutex creates a new Mutex.

func (*Mutex) Lock

func (c *Mutex) Lock(id uint64)

Lock locks the mutex by the given ID. If the mutex is already locked by this ID, Lock blocks until the mutex is available.

func (*Mutex) Unlock

func (c *Mutex) Unlock(id uint64)

Unlock unlocks the mutex by the given ID. It is a run-time error if the mutex is not locked by the ID on entry to Unlock.
