Overview

Fragment of JSON document that is to be included as is:

fragment = JSON::Fragment.new("[1, 2, 3]")
JSON.generate({ count: 3, items: fragments })

This allows to easily assemble multiple JSON fragments that have been persisted somewhere without having to parse them nor resorting to string interpolation.

Note: no validation is performed on the provided string. It is the responsability of the caller to ensure the string contains valid JSON.
