on-demand-ify `custom_coerce_unsized_kind` and `inherent-impls` by nikomatsakis · Pull Request #40683 · rust-lang/rust

nikomatsakis · 2017-03-20T20:31:03Z

This "on-demand" task both checks for errors and computes the custom unsized kind, if any. This task is only defined on impls of CoerceUnsized; invoking it on any other kind of impl results in a bug. This is just to avoid having an Option, could easily be changed.

@eddyb -- I added another commit, converting inherent-impl things.

r? on those commits.

eddyb · 2017-03-20T23:18:50Z

What's this?

yeah, what is that? weird.

oh, that file never got removed...it was supposed to be.

eddyb · 2017-03-20T23:20:35Z

This isn't moved from anywhere else?!

it is, not sure why git didn't figure it out. I split up inherent.rs into two files, since it was doing two things.

I guess I could keep it together. Might be cleaner diff.

What I mean is, you don't have a negative diff on inherent.rs matching the positive diff.

yeah, it's because inherent.rs is all dead now. just pushed a revised version which deleted it.

This "on-demand" task both checks for errors and computes the custom unsized kind, if any. This task is only defined on impls of `CoerceUnsized`; invoking it on any other kind of impl results in a bug. This is just to avoid having an `Option`, could easily be changed.

Top-down, top-down!

There are now 3 queries: - inherent_impls(def-id): for a given type, get a `Rc<Vec<DefId>>` with all its inherent impls. This internally uses `crate_inherent_impls`, doing some hacks to keep the current deps (which, btw, are not clearly correct). - crate_inherent_impls(crate): gathers up a map from types to `Rc<Vec<DefId>>`, touching the entire krate, possibly generating errors. - crate_inherent_impls_overlap_check(crate): performs overlap checks between the inherent impls for a given type, generating errors.

Error in gdb. Seems unlikely to be related to this PR, but not impossible.
