Running tests

bash cargo test

Clippy lints

bash cargo clean ; cargo clippy -- \ -A clippy::suspicious_else_formatting \ -A clippy::unreadable_literal \ -A clippy::unnecessary_mut_passed

Then pick one of the things it complains about and look at all instances of only that.

For example:

bash touch src/lib.rs ; cargo clippy -- -A clippy::all -W clippy::trivially_copy_pass_by_ref
