It's rare to see ANSI escape codes for URLs in the wild, but cargo has it! This example links to https://doc.rust-lang.org/cargo/reference/profiles.html#default-profiles, describing the different profiles. Considering releases vs debug is a source of confusion for new users expecting better performance, this seems wise.

One nice feature of cargo that I wasn't previously aware of: you don't need to do anything after updating your Cargo.toml. In npm, you need to remember to `npm i` after changing package.json. It's not declarative and the state can get out of sync.

Counter-intuitively, if you're writing a parser for a programming language, you need it to be a total function. As soon as you build IDE tooling, you need ASTs from invalid or incomplete input. The parser should return (Ast, List<Error>) rather than Result<Ast, Error>.
