Fix associated types in copy implementations#38152

arielb1 · 2016-12-04T00:05:17Z

Fixes an ICE and an error in checking copy implementations.

src/librustc_typeck/coherence/builtin.rs

nit: maybe separate each arg on its own line?

I'd say just rustfmt this new file and be done with it.

mrhota · 2016-12-04T22:13:35Z

curiously, the test will ICE immediately with Stable rustc on play.rust-lang.org, but will timeout with beta and nightly.

src/librustc/ty/util.rs

Pre-existing, but it seems like it would be nice to give both the variant name and the field name -- can we do that instead?

That's a good idea.

Is this file all code collected from other places, or did you make changes to it? I couldn't tell.

Code moved from coherence::mod.

arielb1 · 2016-12-09T16:55:57Z

How do you rustfmt?

nikomatsakis · 2016-12-10T01:24:30Z

@arielb1 cargo install rustfmt, then run it on the file I think

@arielb1 if you don't feel like running rustfmt, no biggy, but let's rebase :)

src/test/compile-fail/E0204.rs

can we make this a ui test? I'd like to see precisely where the span is, since it's critical to the message

Span the affected fields instead of reporting the field/variant name.

looks great :)
