Crate serde_versioned 

serde_versioned

A library for handling versioned serialization and deserialization of Rust structs. This crate provides traits and derive macros to support multiple versions of data structures while maintaining backward compatibility.

Usage

use serde_versioned::{Versioned, FromVersion};
use serde::{Serialize, Deserialize};

#[derive(Versioned, Serialize, Deserialize, Clone)]
#[versioned(versions = [UserV1, UserV2])]
struct User {
    pub name: String,
    pub age: u32,
}

#[derive(Serialize, Deserialize, Clone)]
pub struct UserV1 {
    pub name: String,
}

#[derive(Serialize, Deserialize, Clone)]
pub struct UserV2 {
    pub name: String,
    pub age: u32,
}

impl FromVersion<User> for UserV1 {
    fn convert(self) -> User {
        User { name: self.name, age: 0 }
    }
}

impl FromVersion<User> for UserV2 {
    fn convert(self) -> User {
        User { name: self.name, age: self.age }
    }
}
