Some rustdoc examples: (#665)

Includes examples for: UdpSocket, bind, local_addr, send_to, recv_from, set_broadcast, broadcast.

Thanks for the PR!

I think including a full example for the struct level docs is probably good, however, for each individual function, would it be possible to reduce down the example to focus on the function as question? This should make it easier to see the relevant bits. Ideally, none of the fn level examples would include a full event loop.

Hey, should the examples hide the event loop with # or should I simply "fake" calls to the functions like:

# Ok(())
socket.send_to(&buffer, &addr);

Or something else entirely?

Woops, it seems like I never clicked "send" for this comment.

Maybe just use 0 / 1 here? The other examples do that and I think we want to try to stick with a single style.

[carllerche]

@lanedraex sticking with fake calls is fine. You can use the no_run annotation I think it is.

[carllerche]

@lanedraex Thanks, these examples look great.

I'll add examples to the other methods.

Also, just noticed that I made a typo in the pull request title, sorry.
