Serde JSON in Rust: Serialization, Pretty Print, and Error Handling is the de facto standard for JSON in Rust. It builds on the framework — a general-purpose serialization/deserialization library — meaning the same derive macros work across JSON, TOML, YAML, MessagePack, and many other formats. If you understand , you understand broadly. Adding serdejson to Your Project The feature enables the macros. Both are needed — provides the framework, provides the JSON implementation. Basic Serialization produces compact output. uses 2-space indentation. Both return . The here is fine for examples — in production code, propagate the error. Serde Attributes Serde attributes control how struct fields are named, filtered, and transformed in the JSON output: is the most commonly used attribute for API…
