Mutex와 ReentrantLock의 차이

[jerry8282]

Mutex의 withLock은

@OptIn(ExperimentalContracts::class)
public suspend inline fun <T> Mutex.withLock(owner: Any? = null, action: () -> T): T {
    contract {
        callsInPlace(action, InvocationKind.EXACTLY_ONCE)
    }
    lock(owner)
    return try {
        action()
    } finally {
        unlock(owner)
    }
}

다음과 같이 suspend function이고

ReetrantLock은

@kotlin.internal.InlineOnly
public inline fun <T> Lock.withLock(action: () -> T): T {
    contract { callsInPlace(action, InvocationKind.EXACTLY_ONCE) }
    lock()
    try {
        return action()
    } finally {
        unlock()
    }
}

다음과 같이 suspend function이 아님
