//! A database access library for leveldb
//!
//! Usage:
//!
//! ```rust,ignore
//! extern crate tempdir;
//! extern crate leveldb;
//!
//! use tempdir::TempDir;
//! use leveldb::database::Database;
//! use leveldb::kv::KV;
//! use leveldb::options::{Options,WriteOptions,ReadOptions};
//!
//! let tempdir = TempDir::new("demo").unwrap();
//! let path = tempdir.path();
//!
//! let mut options = Options::new();
//! options.create_if_missing = true;
//! let mut database = match Database::open(path, options) {
//! Ok(db) => { db },
//! Err(e) => { panic!("failed to open database: {:?}", e) }
//! };
//!
//! let write_opts = WriteOptions::new();
//! match database.put(write_opts, 1, &[1]) {
//! Ok(_) => { () },
//! Err(e) => { panic!("failed to write to database: {:?}", e) }
//! };
//!
//! let read_opts = ReadOptions::new();
//! let res = database.get(read_opts, 1);
//!
//! match res {
//! Ok(data) => {
//! assert!(data.is_some());
//! assert_eq!(data, Some(vec![1]));
//! }
//! Err(e) => { panic!("failed reading data: {:?}", e) }
//! }
//! ```
