type Mutex ¶

type Mutex struct {
	sync.Mutex //nolint:forbidigo // this package wraps sync.Mutex
}

A Mutex is a mutual exclusion lock.

type Pauser ¶ added in v2.11.0

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

Pauser is a thread-safe pause/resume primitive using the closed-channel pattern. When not paused, Wait returns immediately. When paused, Wait blocks until Resume is called or the context is cancelled.

A nil *Pauser is safe to use: Wait always returns nil.

func NewPauser() *Pauser

func (p *Pauser) IsPaused() bool

func (p *Pauser) Pause()

func (p *Pauser) Resume()

func (p *Pauser) Wait(ctx context.Context) error

type RWMutex ¶

type RWMutex struct {
	sync.RWMutex //nolint:forbidigo // this package wraps sync.RWMutex
}

An RWMutex is a reader/writer mutual exclusion lock.
