Serialization has always been a strong point of Rust. In particular, Serde was available well before Rust 1.0.0 was released (though the derive macro was unstable until 1.15.0). The idea behind this is to use traits to decouple the objects and (de)serialize from the serialization format — a very powerful idea. dlg7188rm repair https://loken-engineering.com
