Rustbreak is an Daybreak inspired self-contained file database. It is meant to be fast and simple to use. You add it to your application and it should just work for you. The only thing you will have to take care of is saving.

When to use it

This library started out because of a need to be able to quickly write an application in rust that needed some persistence while still being able to write arbitrary data to it.

In Ruby there is Daybreak however for Rust there was no similar crate, until now!

Features

Simple To Use, Fast, Secure
Threadsafe
Key/Value Storage

Usage

Usage is quite simple:

Create/open a database using Database::open
- You can specify the kind of Key you want using this Syntax: Database::<Key>::open
Insert/Retrieve data from the Database
Don't forget to run flush periodically

use rustbreak::Database;

fn main() {
    let db = Database::open("my_contacts").unwrap();

    db.insert("Lapfox", "lapfoxtrax.com").unwrap();
    db.insert("Rust", "github.com/rust-lang/rust").unwrap();

    // we need to be explicit about the kind of type we want as println! is
    // generic
    let rust : String = db.retrieve("Rust").unwrap();
    println!("You can find Rust at: {}", rust);
    db.flush().unwrap();
}

How it works

Internally the Database holds a Hashmap behind a RwLock. This Hashmap is then written to/read from and safely casted to the requested type. This works thanks to encoding/decoding traits.
