How do you work with JSON in Rust?

Question

Accepted Answer

**serde_json** — JSON serialization/deserialization.

**Serialize:**
```rust
use serde::{Serialize, Deserialize};
use serde_json;

#[derive(Serialize, Deserialize)]
struct User {
    name: String,
    age: u32,
}

let user = User { name: "Alice".into(), age: 30 };
let json = serde_json::to_string(&user)?;
```

**Deserialize:**
```rust
let user: User = serde_json::from_str(&json)?;
```

**Value manipulation:**
```rust
use serde_json::json;

let data = json!({
    "name": "Alice",
    "age": 30
});

let name = data["name"].as_str().unwrap();
```

**Key:** serde for derive, serde_json for operations.
