Serialize/Deserialize style traits

Crates like serde can implement serialization automatically.

Derivable: ✅

When to implement: Almost always.

#![allow(unused)]
fn main() {
#[derive(Serialize, Deserialize)]
struct ExtraData {
    fav_color: String,
    name_of_dog: String,
}

#[derive(Serialize, Deserialize)]
struct Data {
    name: String,
    age: usize,
    extra_data: ExtraData,
}
}
- Provides serialization and deserialization functionality for a type.

  • When not to implement: If a type contains sensitive data that should not be erroneously saved to disk or sent over a network, consider not implementing Serialize/Deserialize for that type.

    Shares security concerns with Debug, but given serialization is often used in networking there can be higher stakes.
