[Andrew Halberstadt [:ahal]]

Just wanted to mention that I had previously looked into this, but using rustfmt (with the checkstyle option) instead:
https://github.com/rust-lang-nursery/rustfmt

But if the rust devs prefer clippy, we should definitely go with that. The only thing I'd ask is to consider somehow integrating this with mozlint:
http://gecko.readthedocs.io/en/latest/tools/lint/index.html

While rustfmt would be easy to integrate with mozlint, clippy would be trickier as it is a compiler extension. So I'm not 100% sure if integration makes sense in this case, or if we should make a brand new thing. And even if mozlint isn't the right fit for this, we could still re-use the existing |mach lint| mach command. Anyway, just something to consider.

I'm not back until the 23rd, but I'd be happy to discuss/answer questions either here or via e-mail until then.

Doing some bug cleanup.

Once we have clippy support for rust stable, I don't think this will need more than one bug to complete, so I'm just turning this into the bug that will implement clippy as a mozlint linter. Doing this will also automatically provide the mach command, so would make bug 1361343 invalid.

clippy cannot run on a single file. it needs to build the file
It can be built using:
cargo clippy --manifest-path js/src/wasm/cranelift/Cargo.toml

Attachment: Bug 1361341 - Move the mozlint job into the mozlint.yml job r?#linter-reviewers

Instead of python.yml
Otherwise, it is getting the incorrect docker image (without rust).
And it makes sense that the mozlint job is next to the other tasks

Depends on D58293
