Mastering Rust’s Result Enum for Error Handling
Mastering Rust’s Result type for safer and cleaner error handling.
Why Do Your URLs Suck?
URL design is the facade project of the API architecture, and it is necessary to find a balance between technical implementation and user experience. By following the three principles of simplicity, semanticization, and compatibility, and combining mature mapping mechanisms and excellent case practices, a URL system that conforms to engineering specifications and has commercial value can be constructed. With the development of the API economy in the future, URL design will carry more business semantics and become an important bridge connecting the system and users.
