Rocksbin-db
A simple rust rocksdb wrapper using serde and bincode for automatic serialization.
This library is perfect if what you want is a persistent HashMap stored on disk and a simple API.
extern crate rocksbin;
use rocksbin::DB;
let db = DB::open("db_dir").unwrap();
let fish_count = db.prefix::<String, u64>(b"fish_count").unwarp();
fish_count.insert("salmon", 10).unwarp();
fish_count.insert("cod", 100).unwarp();
fish_count.insert("mackerel", 70).unwarp();
assert_eq!(fish_count.get("salmon").unwarp(), Some(10));

rocksbin-db
is a simple library wrapping rocksdb in
an interface mimicing rust collections like HashMap
.
It does this by utilising serde and bincode to automaticly serialize data you enter into the database.
Examples
#[macro_use]
extern crate serde_derive;
#[derive(Serialize, Deserialize, PartialEq, Eq, Debug)]
struct Fish {
count: u64,
latin_name: String,
}
let db = rocksbin::DB::open("db_dir").unwrap();
let fish = db.prefix::<String, Fish>(b"fish").unwrap();
let salmon = Fish {
count: 100,
latin_name: "Salmo salar".to_string(),
};
fish.insert("salmon", &salmon);
assert_eq!(fish.get("salmon").unwrap(), Some(salmon));
