The 'store' package provides efficient binary serialization. There are a couple features that particularly distinguish it from most prior Haskell serialization libraries:
Its primary goal is speed. By default, direct machine representations are used for things like numeric values (
Word32, etc) and buffers (
Vector, etc). This means that much of serialization uses the equivalent of
Instead of implementing lazy serialization / deserialization involving multiple input / output buffers,
pokealways work with a single buffer. This buffer is allocated by asking the value for its size before encoding. This simplifies the encoding logic, and allows for highly optimized tight loops.
storecan optimize size computations by knowing when some types always use the same number of bytes. This allows us to compute the byte size of a
Vector Int32by just doing
length v * 4.
It also features:
Optimized serialization instances for many types from base, vector, bytestring, text, containers, time, template-haskell, and more.
