Web Tooling Inspiration
- Charlie Marsh was inspired by the JavaScript ecosystem's innovations.
- Web tooling faced performance challenges, leading to faster tools in languages like Go and Rust, which influenced his approach to Python tooling.
Learning Rust Through Ruff
- Charlie's motivation for creating Ruff was partly to learn Rust by building something from scratch.
- He found that learning Rust's borrow checker was initially challenging, especially when working with abstract syntax trees.
Learning Rust Effectively
- When learning Rust, focus on fundamental concepts before using advanced features like smart pointers.
- Cloning can be a useful tool when starting with Rust, but strive to minimize allocation overhead when building high-performance tools like Ruff.
