FAQ

Are serde attributes included?
Yes. All structs include #[derive(Debug, Serialize, Deserialize)]. Fields that need renaming get #[serde(rename = "...")].
How are field names converted?
CamelCase and kebab-case JSON keys are automatically converted to Rust snake_case, with serde rename attributes to maintain JSON compatibility.
What types are inferred?
String, i64, f64, bool, Vec<T>, and nested struct types are inferred. Null values become Option<serde_json::Value>.
