@hackage tagged-binary0.1.2.0

Very minimal library providing tools for serializing and decoding data into ByteString tagged with information about its type, inspired by Cloud Haskell and distributed-process.

Intended for use by libraries and frameworks in distributed contexts, such as distributed computation between native servers and communication between native servers and ghcjs/various front-ends, for behavior similar to the polymorphic communication channels of Cloud Haskell and distributed-process; servers can send tagged data, and clients can choose to selectively accept, ignore or queue incoming messages depending on their types.

For basic encoding, decoding and categorization, only Data.Binary.Tagged should be necessary. Data.Binary.Tagged.Internal is exported in case you need it.

Quick example:

> let x = encodeTagged (1 :: Int)
> decodeTagged x :: Maybe Bool
Nothing
> decodeTagged x :: Maybe Int
Just 1
