FAQ
How do I convert JSON to a Rust struct?
Paste your JSON and the tool generates Rust structs with the matching serde derives, ready to copy into your project.
Are serde annotations added automatically?
Yes, every struct is annotated with derive Serialize and Deserialize, and field names are adapted to Rust conventions.
How are optional fields handled?
Values that may be missing or null are wrapped in an Option type to respect Rust's type safety.
