It provides efficient, zero-copy serialization of Rust data types to and from formats like JSON. The #[derive(Serialize, Deserialize)] macro generates all the boilerplate code automatically at compile time."},{"question":"What does #[derive(Debug, Serialize, Deserialize)] mean?","answer":"These are derive macros that tell Rust's compiler to automatically generate trait implementations. Debug enables printing structs with println!, Serialize makes the struct convertible to JSON, and Deserialize allows parsing JSON back into the struct."},{"question":"What does the rename_all option do?","answer":"rename_all applies a naming convention to all fields during serialization. For example, rename_all=\"camelCase\" converts Rust snake_case field names to JSON camelCase. This bridges the naming convention gap between Rust and JSON APIs."},{"question":"Why use Option<T> for null values?","answer":"Option<T> is Rust's safe way to represent nullable values. Option<String> means the field can be Some(value) or None. This forces you to handle missing data explicitly, preventing null pointer errors. The tool defaults to this for safety."},{"question":"How do I use the generated structs in my Rust code?","answer":"Copy the generated code into your Rust project. Then use serde_json::from_str::<MyStruct>(json_string) to parse JSON into your struct. The compiler enforces type safety automatically. For serialization, use serde_json::to_string(&my_instance) to convert back to JSON."}],"howTo":[{"title":"Paste your JSON data","description":"Input a JSON object or array in the left panel. The tool parses the structure and infers Rust types: strings become String, integers become i64, decimals become f64, booleans become bool, and null becomes Option<T>."},{"title":"Configure struct options","description":"Set the root struct name (default: Root). Toggle Option<T> wrapping for nullable fields. Enable #[serde(rename_all)] attributes for snake_case or camelCase mapping. Choose between owned String and borrowed &str types."},{"title":"Review generated Rust structs","description":"The right panel shows Rust structs with #[derive(Serialize, Deserialize)] and proper serde attributes. Nested objects become separate named structs. Copy the output into your Rust project alongside your serde dependency."}],"agentContract":{"toolId":"json-to-rust-serde","contractVersion":"2.0.0","remote_callable":true,"remote_mode":"dedicated_api","risk_class":"L","max_input_bytes":131072,"timeout_ms":2000,"supports_streaming":false,"preferred_surface":"dedicated_api","dedicated_api":{"baseUrl":"https://aidevhub.io/api/json-to-rust-serde/","openapiUrl":"https://aidevhub.io/api/openapi.yaml","endpoints":[{"method":"GET","path":"/api/json-to-rust-serde/","summary":"GET json-to-rust-serde"},{"method":"POST","path":"/api/json-to-rust-serde/","summary":"POST json-to-rust-serde"}],"riskClass":"L","inputMaxBytes":131072,"timeoutMs":2000},"runtime":{"endpoint":"/api/tools/run/","methods":["GET","POST"],"queryParams":[{"name":"toolId","required":true,"description":"Tool identifier"},{"name":"a","required":true,"description":"Primary input"}],"postBodyShape":{"toolId":"string","input":"{ a, b?, c?, mode? }"},"exampleGet":"https://aidevhub.io/api/tools/run/?toolId=json-to-rust-serde&a=...","policy":{"riskClass":"L","limit":60,"burst":20,"windowSec":60,"inputMaxBytes":131072,"timeoutMs":2000,"cacheTtlSec":0,"networkEnabled":false,"supportsStreaming":false}}},"relatedTools":[{"id":"tailwind-converter","name":"CSS to Tailwind Converter","url":"/tailwind-converter/","category":"converter"},{"id":"html-to-jsx","name":"HTML to JSX Converter","url":"/html-to-jsx/","category":"converter"},{"id":"color-converter","name":"Color Converter","url":"/color-converter/","category":"converter"},{"id":"json-to-go","name":"JSON to Go Struct","url":"/json-to-go/","category":"converter"},{"id":"json-to-python","name":"JSON to Python Dataclass","url":"/json-to-python/","category":"converter"},{"id":"json-to-typescript","name":"JSON to TypeScript Converter","url":"/json-to-typescript/","category":"converter"}]}}
