range values

[ratmice]

It doesn't look (or at least isn't documented whether or not) Ron supports the rust range syntaxes 0..5 etc, I think it would be nice to support these perhaps.

Yes, this would be greatly appreciated if we could do this.
On the other hand, this is complicating the spec and grammar, so there is a trade-off.
Perhaps, the right path here is making this a RON extension.

IIRC ranges can be deserialized as tuples, that is (0, 5) instead of 0..5.

Given that serde implements this behaviour, I don't see how RON could implement this syntax while limiting it to ranges only.

[ratmice]

@torkleyy I'm not really familiar with the serde code base, so could be misunderstanding, however
it looks to me like it just serializes it as a struct range with fields to and from serialize and there is also a deserialize specific to Range, and that deserialize returns Result<Range,...>, I wouldn't expect a impl Deserialize for Range at all if it was serializing to tuples.

That said, I have yet to actually try it, So holding out hope you are remembering something specific to a data format.

There would be a related problem if it serialized RangeInclusive to the same thing as Range it uses the same to, and from fields, but has a different structure name RangeInclusive so hopefully it seems like we can differentiate those based on the structure name.

@kvark no qualms with an extension if it need be, I'd had a look
