Oh wow, ig someone managed to do the impossible . Still seems to be some errors left to fix though like ``Assertion failed: (((nresults) < (L->top - L->ci->func)) && "not enough elements in the stack"), function lua_yieldk, file ldo.c, line 697.
test test_chunk_env ... ok
error: test failed, to rerun pass `--test thread```

It still has many many issues, as i have to modify callback_error_ext

How exactly does this solve the issue of the Rust/Lua call boundary?

This doesn't, it relies on Err to stop it.

I'm planning to add both this and an async system where Lua acts as the waker.

@radiantgurl @khvzak Have integrated this PR into my general PR for yielding and luau continuations (which go together anyways as you cant use continuations really without the yielding): #588

How do you co author someone on a commit (im new to this type of git stuff)

Also, I didn’t really use much of your code in the end besides the inspiration for yielded_values in extra_args and the is_yieldable bit. The rest had to be reworked a lot (especially to work with luau specific stuff in its continuation implementation) and due to general errors I found when testing/trying to use it (turns out yielding isn’t as easy as it looks lol)

Sorry for not attributing you in advance though
