Topic: Reviving dead trait impl code

I'm trying to fix https://github.com/rust-lang/rust/issues/58375 since it's been... waiting for quite a while

Dirkjan Ochtman (Jun 20 2019 at 19:00, on Zulip):

my hypothesis so far is that since https://github.com/rust-lang/rust/pull/46916/commits/238ed47d290849cb5d37f18dbf15c2433fc88c80 some code that uses the impl has been revived but the impl itself was not

Dirkjan Ochtman (Jun 20 2019 at 19:01, on Zulip):

so could anyone help point out places where unused impls might be killed or whatever?

Also, how do I look at the output from debug!() calls?

you can see the output when using the RUSTC_LOG env variable, more info is available in the rustc-guide here
