EventWriter::flush()

[dvtomas]

It would be handy if EventWriter implemented a flush() method, that would just flush the underlying sink.

My use-case is a long-running measurement application that occasionally saves a complex XML element into a file backed by a BufWriter. I'd like to flush the writer each time I save a new element so I have the relevant info stored in case of failure.

I'd really like an inner() method that returns a mutable reference to the sink. This would let you flush it, and it would let me do things like take over indentation myself with less overhead, as well as do things like emitting doctype tags (since xml-rs doesn't support them; see #168) or other such things.

I realize this would easily let you construct invalid XML, but I'm ok with that.

[dvtomas]

Sure, that would work for me..

Yes, I think adding inner() would be a more generic approach. I agree that it could make emitting invalid XML possible, but it is anyway possible now, because the emitter does not do escaping in some cases. I'll add such a method now.

inner_mut() is now available in 0.8.0, which is released to crates.io. I guess this could be closed. Sorry for the delay!

Great, thank you so much.
