I having difficulty using mutex's custom

[Nghiait123456]

in https://github.com/go-redsync/redsync/blob/master/mutex.go#L17-L34

// A Mutex is a distributed mutual exclusion lock.
type Mutex struct {
	name   string
	expiry time.Duration

	tries     int
	delayFunc DelayFunc

	driftFactor   float64
	timeoutFactor float64

	quorum int

	genValueFunc func() (string, error)
	value        string
	until        time.Time

	pools []redis.Pool
}

Mutex is public, but element of this (name, tries,...) is private, when custom default mutex, i have only one way:

mutex := rs.NewMutex("test-redsync", redsync.OptionFunc(func(mutex *redsync.Mutex) {
		mutex = &redsync.Mutex{
			name:   "test-redsync",
			expiry: 1 * time.Second,
			tries:  32,
			delayFunc: func(tries int) time.Duration {
				return time.Duration(rand.Intn(maxRetryDelayMilliSec-minRetryDelayMilliSec)+minRetryDelayMilliSec) * time.Millisecond
			},
			genValueFunc:  genValue,
			driftFactor:   0.01,
			timeoutFactor: 0.05,
			quorum:        len(r.pools)/2 + 1,
			pools:         r.pools,
		}
		fmt.Println("call f fc")
	}))
	```

it's rich, i only want custom one parram, but i must pass to all param.

Can i help you this problem?
