Rust serde

Serialization

• From struct to json

Deserialization

• From json to struct

Example

struct W {
    a: i32,
    b: i32,
}
let w = W { a: 0, b: 0 }; // Represented as `{"a":0,"b":0}`
 
struct X(i32, i32);
let x = X(0, 0); // Represented as `[0,0]`
 
struct Y(i32);
let y = Y(0); // Represented as just the inner value `0`
 
struct Z;
let z = Z; // Represented as `null`
 
enum E {
    W { a: i32, b: i32 },
    X(i32, i32),
    Y(i32),
    Z,
}
let w = E::W { a: 0, b: 0 }; // Represented as `{"W":{"a":0,"b":0}}`
let x = E::X(0, 0);          // Represented as `{"X":[0,0]}`
let y = E::Y(0);             // Represented as `{"Y":0}`
let z = E::Z;                // Represented as `"Z"`
