Crate rustbreak [−] [src]

Rustbreak

Rustbreak is a Daybreak inspiried single file Database. It uses bincode or yaml to compactly save data. It is thread safe and very fast due to staying in memory until flushed to disk.

It can be used for short-lived processes or with long-lived ones:

use rustbreak::{Database, Result};

fn get_data(key: &str) -> Result<String> {
    let db = try!(Database::<String>::open("/tmp/database"));
    db.retrieve(key)
}

use rustbreak::{Database, Result};

lazy_static! {
    static ref DB: Database<String> = {
        Database::open("/tmp/more_data").unwrap()
    };
}

fn get_data(key: &str) -> Result<u64> {
    DB.retrieve(key)
}

fn set_data(key: &str, d: u64) -> Result<()> {
    let mut lock = try!(DB.lock());
    let old_data : u64 = try!(lock.retrieve(key));
    lock.insert(key, d + old_data)
}
