Crate exonum_rocksdb

Rust wrapper for RocksDB.

Examples

extern crate tempdir;
 extern crate exonum_rocksdb;

 use exonum_rocksdb::DB;
 use tempdir::TempDir;
 // NB: db is automatically closed at end of lifetime
 let temp_dir = TempDir::new("storage").unwrap();
 let db = DB::open_default(temp_dir.path()).unwrap();
 let _ = db.put(b"my key", b"my value");
 match db.get(b"my key") {
    Ok(Some(value)) => println!("retrieved value {}", &value.to_utf8().unwrap()),
    Ok(None) => println!("value not found"),
    Err(e) => println!("operational problem encountered: {}", e),
 }
 db.delete(b"my key").unwrap();
