Notes

Hello,
When i run cargo clippy or cargo check from CLI, I also get warning report for external crate. I'd like to filter this out to get only warning coming from my current project. I Already tried to use -p or --bin _NAME_, but it don't give the result i want.

So, an option to filter out report for external crate would be useful, especially when using cargo clippy -- D OPT in continuous integration tool like travis to enforce particular coding style in a project

Thanks for the report. This is a duplicate of rust-lang/rust-clippy#3025 and #7850 and #5998, so closing in favor of those.
