rust-analyzer to stress-test chalk. Specifically,
Substitute version of chalk ra uses here: https://github.com/rust-analyzer/rust-analyzer/blob/ea3124c12a52f28163a6375b6a5e3c79fc14312d/crates/ra_hir/Cargo.toml#L29-L31
cargo run -p ra_cli --release -- analysis-stats --with-deps ../chalk/
../chalkpoints to the repository to check.
rust-analyzeritself are great candidates
--with-depsinstructs rust-analyzer to also do checking for dependencies, including rust standard library (you should add it with
