It requires a function, which we don't have.

This new function, close is meant to mimic coroutine.close, marking it as finished.

Im assuming Thread::reset marks it as resumable again right?

I don't think it's mlua goal to replicate functionality of Lua standard library.

The idea behind Thread::reset is to provide support of re-using an existing coroutine without creating a new one. And it's used in mlua async implementation to keep a pool of "async" coroutines to avoid extra GC collections and allocations for temporary objects.

I'm currently attempting to use .close() to make sure a thread cannot be resumed again, and that .status() returns Finished
