Example code improvement

I'm not enthusiastic about endorsing .ok().expect(...)...

[GuillaumeGomez]

Hum... Any particular reason ?

[gkoz]

It works here because our error type is () but generally is inferior to Result::expect and seems the opposite of idiomatic. People will use pieces of our examples without questioning them. Maybe we should replace the panic with print! and return.

[GuillaumeGomez]

I'd prefer this actually. I'm not a big fan of panic! when it's not absolutely necessary.

[gkoz]

We should start by updating the actual example(s) anyway and then bring the change here.

[GuillaumeGomez]

Actually, it doesn't seem to be a priority but if you have nothing else waiting, then I let you update examples. ;)

[gkoz]

I'm working on push some hand-generated docs after that maybe.

[GuillaumeGomez]

As you wish, I'm starting to prepare to push on crates.io tomorrow.

[gkoz]

I've found a little issue with the version handling and enums in cairo. Might want to hold off pusblishing crates a bit.

[GuillaumeGomez]

Ok, I'm in standby. Just email me when the situation is unlocked please. ^^

[gkoz]

I've just learnt more about the issue. Good news is, it's not a crates showstopper.

Turns out rustdoc doesn't get the same cfg directives rustc gets so it can't see any of the gated stuff. WAT

[GuillaumeGomez]

DARK MAGIC !!!
Well, I work on crates tomorrow now. Witches will wait !

[gkoz]

Looks like we've resolved this in a different way.
