With this package you can build a Storable instance of a record type from Storable instances of its elements in an elegant way. It does not do any magic, just a bit arithmetic to compute the right offsets, that would be otherwise done manually or by a preprocessor like C2HS. I cannot promise that the generated memory layout is compatible with that of a corresponding C struct. However, the module generates the smallest layout that is possible with respect to the alignment of the record elements. If you encounter, that a record does not have a compatible layout, we should fix that. But also without C compatibility this package is useful e.g. in connection with StorableVector.

We provide Storable instance support for several cases:

Note however that the Storable instances defined with this package are quite slow in (up to) GHC-6.12.1. I'm afraid this is due to incomplete inlining, but we have still to investigate the problem.

For examples see packages storable-tuple and sample-frame.
