Types

type RWMutex

type RWMutex struct {
	*sync.RWMutex
}

RWMutex is a sync.RWMutex with a switch for concurrent safe feature. If its attribute *sync.RWMutex is not nil, it means it's in concurrent safety usage. Its attribute *sync.RWMutex is nil in default, which makes this struct mush lightweight.

func Create

func Create(safe ...bool) RWMutex

Create creates and returns a new RWMutex object. The parameter <safe> is used to specify whether using this mutex in concurrent safety, which is false in default.

func New

func New(safe ...bool) *RWMutex

New creates and returns a new *RWMutex. The parameter <safe> is used to specify whether using this mutex in concurrent safety, which is false in default.

func (*RWMutex) IsSafe

func (mu *RWMutex) IsSafe() bool

IsSafe checks and returns whether current mutex is in concurrent-safe usage.

func (*RWMutex) Lock

func (mu *RWMutex) Lock()

Lock locks mutex for writing. It does nothing if it is not in concurrent-safe usage.

func (*RWMutex) RLock

func (mu *RWMutex) RLock()

RLock locks mutex for reading. It does nothing if it is not in concurrent-safe usage.

func (*RWMutex) RUnlock

func (mu *RWMutex) RUnlock()

RUnlock unlocks mutex for reading. It does nothing if it is not in concurrent-safe usage.

func (*RWMutex) Unlock

func (mu *RWMutex) Unlock()

Unlock unlocks mutex for writing. It does nothing if it is not in concurrent-safe usage.
