Reviewdog is an automated review tool. It extracts relevant parts for the patch from an output of an external linter, and reports the result in several formats, including GitHub Checks and GitHub comments.
clippy-reviewdog-filter is a simple filter for feeding Reviewdog an output of Clippy, the official linter for Rust.
No more interesting than simply running Clippy if you run this locally, but if you want to try this out before putting this into a CI:
Install reviewdog: get the binary release or
$ go get -u github.com/haya14busa/reviewdog/cmd/reviewdog
Install clippy-reviewdog-filter: get the binary release or
$ cargo install --git https://github.com/qnighy/clippy-reviewdog-filter.git
cargo clippy --message-format json 2>&1 | clippy-reviewdog-filter | reviewdog -f=checkstyle -diff="git diff master"

format: checkstyleIf you want to use the github-pr-review reporter in .travis.yml, you're essentially going to publish your API Token to the submitters of pull requests, as they're free to run modified versions of .travis.yml on your Travis CI repo.
For better security, you may want to use the github-pr-check reporter instead or run reviewdog -reporter=github-pr-review in a more isolated environment, like in a dedicated GitHub Webhook server.
Of course, there's no problem with using github-pr-review in a private repository with no forks. In that case, you can just encrypt the github token using the travis encrypt command.
