include rust_coroutines?

[vitiral]

I would really like to include lightweight coroutines and am wondering if rust_coroutines is the right balance of simplicity and performance. I am a little hesitant since may theoretically promises better performance -- but is totally unsafe for now. I suppose we could expose only a cospawn or go or something and just swap it out once may is more safe?

Looking for thoughts on this.

hmm... it seems to be written in C and has some issues with building. More investigation is necessary.
