Name: generic-deepseq Version: 2.0.0.0 x-revision: 1 License-File: LICENSE License: BSD3 Author: Maxime Henrion Copyright: 2012, Maxime Henrion Maintainer: Maxime Henrion Bug-Reports: http://bitbucket.org/mumux/generic-deepseq/issues/ Category: Control, Generics Synopsis: Generic deep evaluation of data structures Build-Type: Simple Cabal-Version: >= 1.6 Tested-with: GHC ==7.4.1 Description: This package provides a 'deepseq' function analogous to 'seq', except that it traverses the entire data structure, evaluating it fully, and not just up to head normal form. . Using lists as an example: . > > [1,2,undefined] `seq` 3 > 3 . Whereas with 'deepseq': . > > [1,2,undefined] `deepseq` 3 > *** Exception: Prelude.undefined . Unlike the @deepseq@ package, this implementation is based on the "GHC.Generics" framework as found in GHC >= 7.2, so that it can generate instances automatically for any datatype that has a 'Generic' instance, without further code. . > data MyType = MyType String Int (Maybe Double) > deriving Generic > instance DeepSeq MyType . Changes in version 2.0.0.0: . * Vastly improved performance. As a consequence of these changes, the member function of the DeepSeq class is now 'rnf', instead of 'deepseq'. . * New instances for functions, Ratio and Complex types.
