Description

Deprecated: This module will be REMOVED in version 0.7.0.0. Please switch to GHC generics or Data.Aeson.TH instead. These alternatives are less buggy, faster, and more configurable.

JSON handling using Generics .

This is based on the Generic package originally written by Lennart Augustsson.

Synopsis

decode :: Data a => ByteString -> Maybe a
decode' :: Data a => ByteString -> Maybe a
encode :: Data a => a -> ByteString
fromJSON :: Data a => Value -> Result a
toJSON :: Data a => a -> Value

Decoding and encoding

decode :: Data a => ByteString -> Maybe aSource

Efficiently deserialize a JSON value from a lazy ByteString . If this fails due to incomplete or invalid input, Nothing is returned.

This function parses immediately, but defers conversion. See json for details.

decode' :: Data a => ByteString -> Maybe aSource

Efficiently deserialize a JSON value from a lazy ByteString . If this fails due to incomplete or invalid input, Nothing is returned.

This function parses and performs conversion immediately. See json' for details.

encode :: Data a => a -> ByteString Source

Efficiently serialize a JSON value as a lazy ByteString .

Lower-level conversion functions

fromJSON :: Data a => Value -> Result aSource

toJSON :: Data a => a -> Value Source
