store

The 'store' package provides binary serialization of Haskell datatypes. It fills quite a different niche from packages like 'binary' or 'cereal'. In particular:

• Its primary goal is speed. Whenever possible, direct machine representations are used. For numeric types (Int, Double, Word32, etc) and types that use buffers (Text, ByteString, Vector, etc). This means that much of serialization uses the equivalent of memcpy.

• By using machine representations, we lose serialization compatibility between different architectures. Store could in theory be used to describe machine-independent serialization formats. However, this is not the usecase it's currently designed for (though utilities might be added for this in the future!)

• Store will not work at all on architectures which lack unaligned memory access (for example, older ARM processors). This is not a fundamental limitation, but we do not currently require ARM support.

See this blog post which describes the initial motivations and benchmarks that led to the existence of this package.
