Automatic min and max in json schema for integers

[autoantwort]

Numbers in json have no limit, but the integers we are parsing into have one.
If no limit is specified explicitly, the default std::numeric_limits::min/max values should be used.
One could always set https://json-schema.org/understanding-json-schema/reference/numeric#range in addition to the allOf property

There is a rfl::capnproto::schema::UInt8 but it is not used in the Schema or did I miss something?

@autoantwort , the problem I have with that is that it adds overhead. But I think we could offer a validator that automatically does that for you, something like:

struct MyStruct {
    rfl::CheckMinMax<int> my_field;
};

(But maybe with a better name.)

Do you mean overhead in the schema, compilation overhead or parsing overhead?

@autoantwort , sorry, I misunderstood the issue. I think this is very possible.
