It's such a shame that many of these standards ignore or are ignorant of the elementary and fundamental sum type. Instead I am left needing to employ some ad-hoc encoding using string tags or similar.
- dmcg 9y agoDoes oneOf not cover it?
- willtim 9y agooneOf looks like it could be used to encode sum types together with a custom string tag, but that's not the first class treatment that records get.
- henryluo 9y agoMark (https://mark.js.org https://mark.js.org) is a new notation that extends JSON with a type-name, which can be a more structured way to encode type info, instead of using custom string tag.
- deathanatos 9y agoI agree wholeheartedly (I have so many use cases for a sum type!), but I think that opportunity was lost when JSON itself was created; JSON-schema, built on top of JSON, would have to make some assumptions about how to map any sum type onto JSON, since JSON doesn't natively support them. JSON-schema — reasonably, I think — doesn't.
