rusty_leveldb/
lib.rs

1//! rusty-leveldb is a reimplementation of LevelDB in pure rust. It depends only on a few crates,
2//! and is very close to the original, implementation-wise. The external API is relatively small
3//! and should be easy to use.
4//!
5//! ```
6//! use rusty_leveldb::{DB, DBIterator, LdbIterator, Options};
7//!
8//! let opt = rusty_leveldb::in_memory();
9//! let mut db = DB::open("mydatabase", opt).unwrap();
10//!
11//! db.put(b"Hello", b"World").unwrap();
12//! assert_eq!(b"World", &*db.get(b"Hello").unwrap());
13//!
14//! let mut iter = db.new_iter().unwrap();
15//! // Note: For efficiency reasons, it's recommended to use advance() and current() instead of
16//! // next() when iterating over many elements.
17//! assert_eq!((b"Hello".to_vec(), b"World".to_vec()), iter.next().unwrap());
18//!
19//! db.delete(b"Hello").unwrap();
20//! db.flush().unwrap();
21//! ```
