Funny to see this now. I’ve got a private branch I am in the process of shaping up this weekend to show the compiler team. For deep nested projects like rust analyzer, if you emit the meta data about function types earlier for downstream slots to use, before successful type checking, you can start other crates earlier and use all the slots you have instead of sitting around waiting for the full type checking of the bodies (which other crates largely don’t care about). Something like 40% wall time speed up, maybe 10% to 15% if you have the parallel frontend on.
Sounds lovely, give it a try on the codex-rs which seems to be getting close to using 2K crates in their repository any time now. Takes like 30 minutes to compile on a my beefy machine and it's a goddamn TUI, not sure what's going on, and not too interested in diving into that beast either.
Sure, that compiles in a few minutes for me too, give it a try with a release build and compiling the full workspace though, since the point here is to stress the compiler :)
