# Lint the source itself (lib + bins). This skips the 42 integration test
# binaries and the `#[cfg(test)]` modules inside src/, which together are ~45
# extra compilation units — nearly all of them link steps, and the reason a
# commit used to sit on "Building [===>] 733/783". Test code is still linted
# and type-checked on push.

# CARGO_TARGET_DIR keeps clippy out of the directory `cargo test` and `cargo
# build` use. Clippy runs a different rustc wrapper, so sharing a target dir
# makes the two invalidate each other's cache and rebuild the world on every
# alternation.
