Module serde_with::rust::display_fromstr

De/Serialize using Display and FromStr implementation

This allows to deserialize a string as a number. It can be very useful for serialization formats like JSON, which do not support integer numbers and have to resort to strings to represent them.

Examples

#[derive(Deserialize, Serialize)]
struct A {
    #[serde(with = "serde_with::rust::display_fromstr")]
    address: Ipv4Addr,
    #[serde(with = "serde_with::rust::display_fromstr")]
    b: bool,
}

let v: A = serde_json::from_str(r#"{
    "address": "192.168.2.1",
    "b": "true"
}"#).unwrap();
assert_eq!(Ipv4Addr::new(192, 168, 2, 1), v.address);
assert!(v.b);

let x = A {
    address: Ipv4Addr::new(127, 53, 0, 1),
    b: false,
};
assert_eq!(r#"{"address":"127.53.0.1","b":"false"}"#, serde_json::to_string(&x).unwrap());
