Os serializer

[oa-metaswitch]

Hi all.

I started working on a serializer a while back, and didn't realize that a different version had been submitted in the meantime. Unfortunately mine behaves a bit differently, so it would be difficult to merge it with the other serializer.

I thought I'd submit the code I have, though. It's reasonably feature complete, with support for maps, structs, tuples, and their various combinations, as well as sequences and XML namespaces.

Any chance this could be of use?

phew... could you run rustfmt? It's very hard to check out with all these unrelated formatting changes.

[oa-metaswitch]

Sorry about that.

My version of rustfmt seems happy with those changes. Should I be running with a particular version of rustfmt?

[oli-obk]

Are you using rustfmt-nightly or rustfmt?

[oa-metaswitch]

Looks like I'm using rustfmt. I'll try to run rustfmt-nightly and see how that goes. Thanks. :) [edited because I had it backwards]

[oa-metaswitch]

That did the trick. Thanks. :)

As an interested third party, is this PR likely to get merged at any point in the near future?

@RReverser: sorry to bother you again, but it's been a year and I'm keen that this thread doesn't go stale. It doesn't look like the serde feature is going to happen anytime soon, so would it make sense to either merge this as is or make some change so we can support both list types?

Looking at the PR, I noticed that xml_rs is not used to serialize, rather xmltree which requires keeping the whole DOM tree in memory before writing to a String or Write implementation.

This is clearly not scalable.

I would rather use the xml_rs writer to implement serialization. The only difficulty I've found is handling attributes.
