implement the chalk-engine traits #50937

nikomatsakis · 2018-05-21T13:14:04Z

Preliminary implementation for the Chalk traits in rustc. Lots of panic!() placeholders to be filled in later.

This is currently blocked on us landing rust-lang/chalk#131 in chalk and issuing a new release, which should occur later today.

travis failures look spurious.

pietroalbini · 2018-05-24T21:48:47Z

That error is caused by travis itself (it wasn't able to download a ruby gem it needs to deploy things).

implement the chalk-engine traits Preliminary implementation for the Chalk traits in rustc. Lots of `panic!()` placeholders to be filled in later.
