@phansch
Don't trigger missing_const_for_fn in external macros
b87f5bc 
As reported in rust-lang#3841. Only fixes the part where it triggers on the
`derive`.

Refactor: Extract `trait_ref_of_method` function

This pattern was used in three places after rust-lang#3844, so I think it's worth moving it into `utils/mod.rs` and documenting it.

@phansch Any timeline for this fix to go live? Running rustup component add clippy followed by cargo clippy --version gives 2019-03-03 (0.0.212) — before this patch was applied.

@jhpratt It's currently included in Rusts beta channel and should hit stable with Rust 1.35 on May 23rd. (It's unlikely that it will be included in a possible 1.34.1 release as it's a disabled-by-default lint)

It's not available on nightly beforehand? I guess that's where my confusion is at.

Oh I misunderstood the Clippy version. It should be available in nightly after nightly-2019-03-12.
