Option to return immediately if lock is taken

[indeyets]

I have a workflow, which would benefit if it were possible to try to get the lock and fail immediately if it is taken by other greenlet.

Would you take a patch implementing this?

There are 2 ways to implement this:

1. return Promise<bool> (true = success, false = failure)
2. throw exception on failure, leave everything as-is on success

[ide]

• Do you want a customizable timeout?
• Do you want to wait for one tick of the event loop to try and acquire the lock, or do you want to immediately acquire the lock synchronously?

I don't

Do you want to wait for one tick of the event loop to try and acquire the lock, or do you want to immediately acquire the lock synchronously?

No preference, actually. Both are fine for me

Published tryAcquire in 1.2.0: https://github.com/ide/await-lock/releases. See the code for documentation, though it's pretty straightforward.
