try_take

[marvin-j97]

Is it possible for guardian to implement something like Mutex::try_lock (try_take?), that doesn't block the thread if it can't take the mutex immediately? I have a situation where I have multiple mutexes that may or may not be blocked, and I want to iterate through them to find an open lock. With guardian that is currently not possible, but it would be nice to get the lifetime-free lock guard.

Hmm, yes, I think that should be doable! You'd just want a variant of

guardian/src/lib.rs

Line 216 in 2460e84

macro_rules! take {

That calls try_lock and returns an Option. I'm a bit short on time at the moment, but would be happy to review a PR!
