gps.rs: Use the ? operator instead of a match or try!() #1

Closed federicomenaquintero closed 7 years ago

federicomenaquintero commented 7 years ago

Protip: try!(foo) is equivalent to "foo?".

@federicomenaquintero wow! thanks that does look much better and ? is indeed exactly what I needed. I did find the mention of ? operator in try! docs but it's hard to find docs on ? for obvious reasons. :)

I took the liberty of modifying your commit log, I hope you don't mind.

Heh - the only reference I found to ? was in https://doc.rust-lang.org/reference.html#unary-operator-expressions - I saw some example code use it. I didn't really look in the try! docs. The "Error handling" chapter in the stable rust book doesn't mention it. Maybe the new book (which is awesome) will!
