# ctypes bindings for LevelDB
The existing three [LevelDB](http://code.google.com/p/leveldb/) interfaces ([py-leveldb](http://code.google.com/p/py-leveldb/), [cpy-leveldb](https://github.com/forhappy/cpy-leveldb), [plyvel](https://github.com/wbolster/plyvel/)) use the Python C API and compile Python modules that work with LevelDB's C++ interface. This Python module simply uses the ctypes library to LevelDB's C interface - making it more portable across Python implementations and easier to install and distribute.
lvldb:
* Python 2-3 compatible
* supports get/put/delete (with standard read/write options)
* supports bloom filters
* supports leveldb LRU cache
* allows for manual or automatic database closing (compare with py-leveldb)
* provides write batches
* provides iterators (full control of leveldb iteration, with additional idiomatic python iterator support)
* provides prefix-based iteration (returns iterators that work as if all keys with a shared prefix had the prefix stripped and were dumped into their own database)
* provides scoped sub-databases (presents a new database wrapper backed by an existing database with all keys prefixed by some prefix)
* provides range iterators (for idioms like give me all keys between start and end)
* provides an in-memory db implementation (for faster unit tests)
* supports snapshots
* fits in one file
* requires no compilation
## Sample Usage
```
# Python3
import lvldb
db = lvldb.DB("/path/to/db", create_if_missing=True)
db.put("key1", "value1")
db.put("key2", "value2")
print(f"key1 => {db.get('key1')} ")
for key, value in db:
print(f"{key} => {value}")
```
