Implent Serialize/Deserialize for Range

[rocallahan]

... when T is Serialize/Deserialize, of course.

Any preference for what the representation would be? Something like 3..6 could be either

[3, 4, 5]

... or

{
  "start": 3,
  "end": 6
}

Another important thing to consider is whether people will ever need to deserialize a range without knowing ahead of time whether it is Range or RangeFrom or RangeTo or RangeFull.

Can you provide a bit more detail about your use case for this?

That's all a Range is.

No idea, but that would only come up when you consider whether/how to implement Serialize/Deserialize for RangeArgument, which isn't even stable yet.

Can you provide a bit more detail about your use case for this?

I have a struct containing a field that's of type Range<MyLocalType> and I want to auto-derive Serialize and Deserialize for it, but I can't. I can't implement Serialize/Deserialize for Range<MyLocalType> in my own crate because of the orphan rules.

Any plans for RangeFrom, RangeInclusive...?
