Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @estebank (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

Failure is reproduced also on my machine.
I misunderstood the way to test a compiler.
I'll try to fix.

seiyab · 2020-03-01T12:45:48Z

I may stuck.
Is this because the feature impl_trait_in_bindings is incomplete ... ?
I'll read rustc code more for the time being.

estebank · 2020-03-11T17:11:18Z

Try running the test that is failing in isolation with your built rustc. When doing so, set RUST_BACKTRACE=1 so that you can see the backtrace of where the error is coming from.

I believe what might be happening is that let res = self.tables.qpath_res(qpath, id); gives you a Res corresponding to the original crate, and not its local import. I am not entirely sure how to help with this, I'll have to dig deeper. @petrochenkov might have better insight on how to proceed here.

seiyab · 2020-03-12T15:42:03Z

Thank you for your comment.

In my interpretation, let res = self.tables.qpath_res(qpath, id); searches on the TypeckTable of owner fn foo ... but it requires to search on the TypeckTable of owner impl FooLike<Output = T::Assoc> .

Here is output of --hir-tree where I think to be related

All I found is I need understand rust and rustc more...

seiyab · 2020-03-16T13:48:45Z

I'm still reading rustc code.
I think OpaqueTybecomes owner in HIR , but the Visitor seems not to update TypeckTable.
