generic-deepseq: Generic deep evaluation of data structures
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
> [1,2,undefined] `deepseq` 3 *** Exception: Prelude.undefined
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
without further code.
data MyType = MyType String Int (Maybe Double) deriving Generic instance DeepSeq MyType
Changes in version 184.108.40.206:
Vastly improved performance. As a consequence of these changes, the member function of the DeepSeq class is now
rnf, instead of
New instances for functions, Ratio and Complex types.
Changes in version 220.127.116.11:
Fix the U1 and V1 instances.
