§Examples
use rocksdb::DB;
// NB: db is automatically closed at end of lifetime
let db = DB::open_default("path/for/rocksdb/storage").unwrap();
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();Re-exports§
