leveldb-haskell: Haskell bindings to LevelDB

[ bsd3, database, ffi, library ] [ Propose Tags ] [ Report a vulnerability ]

From http://leveldb.googlecode.com:

LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values.

This library provides a Haskell language binding to LeveldDB. It is in very early stage and has seen very limited testing.

Note: as of v1.3, LevelDB can be built as a shared library. Thus, as of v0.1.0 of this library, LevelDB is no longer bundled and must be installed on the target system (version 1.7 or greater is required).

Readme for leveldb-haskell-0.2.0

[back to package description]

This library provides Haskell bindings to LevelDB

History

Version 0.2.0:

  • requires LevelDB v1.7
  • support for filter policy (LevelDB v1.5), either custom or using the built-in bloom filter implementation
  • write batch values no longer require a memcpy to be early-finalizer-safe (introduced in 0.1.1)

Version 0.1.0:

  • memory (foreign pointers) is managed through ResourceT. Note that this requires to lift monadic actions inside the MonadResource monad, see the examples.
  • links against shared library (LevelDB v1.3 or higher)
  • LevelDB 1.3 API fully supported (including custom comparators, excluding custom environments)

Version 0.0.x:

  • experimental releases

Installation

Prerequisites:
