# Main CI pipeline to validate PRs.
#
# CI pipeline based on:
# - https://github.com/heim-rs/heim/blob/master/.github/workflows/ci.yml
# - https://github.com/BurntSushi/ripgrep/blob/master/.github/workflows/ci.yml
# - https://www.reillywood.com/blog/rust-faster-ci/
#
# CI pipeline should do:
# - cargo fmt on supported platforms
# - cargo test on supported platforms, cargo check on unsupported
# - cargo clippy after (apparently faster) on supported platforms
