Chaining setters?

[mdboom]

Very new to rust, and think this library is really cool.

I wonder if it would be possible to have setters return a reference to self, such that you could chain setters, e.g.:

obj
   .set_foo(2)
   .set_bar(3);

I think this would be possible!

We'd have to modify https://github.com/Hoverbear/getset/blob/master/src/setters.rs#L28 and https://github.com/Hoverbear/getset/blob/master/src/setters.rs#L38.

Btw, I use getset a lot in combination with delegatemethod and have issues with leaked &mut Self access to members which I don't want:
crlf0710/delegatemethod-rs#6

I'd prefer if there was a way to turn off the chainability (returning &mut Self) in the attribute when specifying the setters. Or if chaining wasn't even the default but could be enabled in that attrib with e.g. #[set = "."]/#[set = ".pub"] (I never use chaining anyway).

@Boscop Hi! That sounds like a very valid feature. How about #[set = "chain pub"]? I would be happy to accept a pr for that!
