![]() ![]() To decode flat encoded data you need to know the type of the serialised data. Acknowledgementsįlat reuses ideas and readapts code from various packages, mainly: store, binary-bits and binary and includes bug fixes from a number of contributors. Get in touch if you would like to help porting flat to other languages. Rust and TypeScript-JavaScript ports are under development. Keep your serialisation code in separate modules. If you have many data types or very large ones, you might want to:ĭuring development, turn optimisations off ( stack -fast or -O0 in the cabal file). This unfortunately leads to longer compilation times. To improve performance, flat relies on extensive inlining. Compatibilityĭata types with more than 512 constructors are currently unsupported (but support could be easily added if necessary) Get the latest stable version from hackage. Transfer time (serialisation time + transport time on the network + deserialisation at the receiving end): flat is usually faster for all but the highest network speeds.Deserialization time: store, flat, persist and cereal are faster.Serialization time: store, persist and flat are faster.Size: flat produces significantly smaller binaries than all other libraries (3/4 times usually).How To Use It For Fun and Profit ĭata Direction = North | South | Center | East | West deriving (Show,Generic,Flat)Īnd unflat to decode: unflat (flat ) :: Decoded Īnd thanks to Flat's bit-encoding, this list fits in 1 byte (rather than the 5 bytes that would be required by a traditional byte encoding): flatBits įor some hard data, see this comparison of the major haskell serialisation libraries.
