Types ¶

type MutexBool ¶

type MutexBool struct {
	sync.Mutex
	V bool
}

MutexBool is a thread-safe bool.

func (*MutexBool) Locked ¶

func (m *MutexBool) Locked(f func())

Locked locks the bool.

type MutexInt ¶

type MutexInt struct {
	sync.Mutex
	V int
}

MutexInt is a thread-safe int.

func (*MutexInt) Locked ¶

func (m *MutexInt) Locked(f func())

Locked locks the int.

type MutexString ¶

type MutexString struct {
	sync.Mutex
	V string
}

MutexString is a thread-safe string.
