Waargonaut.Types.JObject.JAssoc

Types and functions for handling our representation of a key:value pair in a JSON object.

Key/value pair type

data JAssoc ws a

This type represents the key:value pair inside of a JSON object.

It is built like this so that we can preserve any whitespace information that may surround it.
