An OSUnfairLock is a wrapper around an unfair lock that locks around accesses to a stored object. It has the same API as OSAllocatedUnfairLock.

Despite being a struct, it isn’t a value type, as copied instances control the same underlying lock allocation.

Prefer storing state protected by the lock in State. Containing locked state inside the lock helps track what is protected state and provides a scope where it is safe to access that state.

When using OSUnfairLock with external state, nonscoped locking allows more flexible locking patterns by using lock() / unlock(), but offers no assistance in tracking what state is protected by the lock.

This lock must be unlocked from the same thread that locked it. As such, it is unsafe to use lock() / unlock() across an await suspension point. Instead, use withLock to enforce that the lock is only held within a synchronous scope.

If you are using a lock from asynchronous contexts only, prefer using an actor instead.

This lock is not a recursive lock. Attempting to lock it again from the same thread while the lock is already locked will crash.
