Methods

acquire(): Promise<MutexId>

Acquires the mutex, waiting if necessary for it to become free if it is already locked. The returned promise is fulfilled once the lock is acquired.

After acquiring the lock, you must call release when you are done with it.

release(mutexId: MutexId): void

Releases the lock and gives it to the next waiting acquirer, if there is one. Each acquirer may release the lock exactly once. If the UUID passed in doesn't match the current lock holder this will throw an error.
