Here are the changes to Rayon required, which I propose publishing in a rustc-rayon crate. I'd like @cuviper or @nikomatsakis to look over that.

Looks great, @Zoxc! It's very nice how well this is integrated with Rayon's abstractions.

I hope we can clean up the handling of thread-local state in the future. All this setting and forwarding is becoming a bit unwieldy.

I took a quick look at the changes to Rayon and they look sensible to me but @nikomatsakis still needs to review them before we can merge this.

Maybe Box<TransCrate + sync::Send> could get a type alias like CrateStoreDyn to clean things up.

I've moved the creation of the thread-pool to an earlier stage, so TransCrate does not require Send.

Did you ever get to the bottom of why this is necessary?

Apparently it is this bug: #48406

michaelwoerister · 2018-05-04T15:31:35Z

Ideally we would merge the rayon changes into upstream if they seem general purpose enough.

I'm curious if there was an actual approval being made.

@michaelwoerister approved it by IRC

Also, I'm against coroutines due to the underlying implementation complexity, primarily regarding soundness.

This version of Rayon doesn't use coroutines.
