This post provides guidelines for choosing between `String` and `&str` in Rust. It introduces four levels of recommendations: using `String` by default, preferring `&str` for function parameters, sometimes returning `&str`, and considering `&str` in structs only when necessary. These rules help simplify code and manage string ownership and lifetime effectively.
