This reverts commit 9761168. False positive has been fixed in newer nightly.

Seems rustfmt somehow checks the crates in /usr/local/cargo/registry/src/github.com-1ecc6299db9ec823/, but I'm not sure about how to fix or reproduce it:

@taiki-e that is very odd... adding clippy does this?

carllerche · 2019-07-21T18:00:20Z

Does this happen on master?

taiki-e · 2019-07-21T18:49:05Z

Currently, I think eb4d80a (bump rustc version to nightly-2019-07-19) is related because rustfmt error did not occur in 9761168.

However, no problems occurred in locally with either branch.

I opened #1338 to check it.

Thanks! Looking good 👍

I added thoughts inline. Also, could we avoid file level allows in favor of adding them on the item? I'm not sure what they are referencing. thanks!

I recommended removing this lint: rust-lang/rust-clippy#4295

We probably should just disable this lint at the project level. This can happen in this PR or follow up work.

Done in ae3bd60.

carllerche

Thanks 👍

I think most of the allow bits (that are not false positives) can be removed. That can happen here or later. I approved, so feel free to merge if you are happy.

mio 0.7 changed this to pass by value 👍 : tokio-rs/mio#894

taiki-e · 2019-07-24T07:58:51Z

@carllerche I have removed all of allow(clippy::..) that are not false positives. (They were much easier than I had imagined. I thought it would cause other warnings but it did not happen.)
