Distribution.Client.Utils.Json

Description

Minimal JSON / RFC 7159 support

The API is heavily inspired by aeson's API but puts emphasis on simplicity rather than performance. The ToJSON instances are intended to have an encoding compatible with aeson's encoding.

Synopsis

data Value
- = Object !Object
- | Array [Value]
- | String String
- | Number !Double
- | Bool !Bool
- | Null
type Object = [Pair]
object :: [Pair] -> Value
type Pair = (String, Value)
(.=) :: ToJSON v => String -> v -> Pair
encodeToString :: ToJSON a => a -> String
encodeToBuilder :: ToJSON a => a -> Builder
class ToJSON a where
- toJSON :: a -> Value

Documentation
