    score: f64,
    address: Address,
    skills: Vec<serde_json::Value>,

struct Address {
    city: String,
    zip: String,
}

Type Inference

i64, f64, String, bool — chosen automatically from your values.

Serde Ready

Derives Serialize & Deserialize for every struct.

Vec<Value>

Arrays map to Vec<serde_json::Value> for flexibility.
