func GoroutineID Uses

func GoroutineID() int64

GoroutineID returns the current goroutine's ID. Use of this function is almost always a terrible idea. It is also very slow. GoroutineID is intended only for debugging. In particular, it is used by syncutil.

type RWMutexTracker Uses

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

RWMutexTracker is a sync.RWMutex that tracks who owns the current exclusive lock. It's used for debugging deadlocks.

func (*RWMutexTracker) Holder Uses

func (m *RWMutexTracker) Holder() string
