Serde Integration

The generated structs use serde's Serialize and Deserialize derive macros, the standard way to handle JSON in Rust. Fields that need renaming (e.g., camelCase JSON keys to snake_case Rust fields) get #[serde(rename = "...")] attributes automatically.

// JSON input
// { "name": "Alice", "age": 30, "active": true }

// Generated Rust struct
use serde::{Deserialize, Serialize};

#[derive(Debug, Serialize, Deserialize)]
struct User {
    name: String,
    age: i64,
    active: bool,
}

// Usage
let json = r#"{"name":"Alice","age":30,"active":true}"#;
let user: User = serde_json::from_str(json).unwrap();
println!("{:?}", user);

Rust Type Mapping

JSON strings map to String, booleans to bool, integers to i64, floats to f64, arrays to Vec<T>, and null values to Option<serde_json::Value>. Nested objects become separate pub structs.

Ownership and Public Fields

All fields are generated as pub for easy access. String types use owned String rather than &str since JSON deserialization typically produces owned data. You can adjust visibility and lifetimes as needed.
