Encode a Value, you can use this function with toValue to get encodeJSON with a small overhead.

Escape text into JSON string and add double quotes, escaping rules:

   '\b':  "\b"
   '\f':  "\f"
   '\n':  "\n"
   '\r':  "\r"
   '\t':  "\t"
   '"':  "\""
   '\':  "\\"
   '/':  "\/"
   other chars <= 0x1F: "\u00XX"

This builder try to render integer when (0 <= e < 1024), and scientific notation otherwise.

Use : as separator to connect a label(no need to escape, only add quotes) with field builders.

Use : as separator to connect a label(escaped and add quotes) with field builders.

A JSON value represented as a Haskell value.

The Object's payload is a key-value vector instead of a map, which parsed directly from JSON document. This design choice has following advantages:

• Allow different strategies handling duplicated keys.
• Allow different Map type to do further parsing, e.g. FlatMap
• Roundtrip without touching the original key-value order.
• Save time if constructing map is not neccessary, e.g. using a linear scan to find a key if only that key is needed.
