This is the documentation for savefile

Introduction

Savefile is a rust library to conveniently, quickly and correctly serialize and deserialize arbitrary rust struct and enums into an efficient and compact binary version controlled format.

The design use case is any application that needs to save large amounts of data to disk, and support loading files from previous versions of the program (but not from later versions!).

Example

extern crate savefile;
use savefile::prelude::*;

#[macro_use]
extern crate savefile_derive;
use std::fs::File;
use std::io::prelude::*;


#[derive(WithSchema,Serialize,Deserialize)]
struct Player {
    name : String,
    strength : u32,
    inventory : Vec<String>,
}

fn save(player:&Player) {
    let mut f = File::create("save.bin").unwrap();
    Serializer::store(&mut f, 0, player);
}

fn load() -> Player {
    let mut f = File::open("save.bin").unwrap();
    Deserializer::fetch(&mut f, 0)
}

fn main() {
    save(&Player { name: "Steve".to_string(), strength: 42,
        inventory: vec!(
            "wallet".to_string(),
            "car keys".to_string(),
            "glasses".to_string())});
    assert_eq!(load().name,"Steve".to_string());
