One of the more interesting semi-recent additions to stable rust is the question mark operator. It's not covered in this Rust Error Handling article, but it's got some of the early-exit appeal of exceptions without too much unwind magic.
Unfortunately I haven't been able to get the question mark operator to work yet with my code, but it looks appealing. It's not 100% obvious to me what qualities my Result type needs in order to be able to make it work. Or whether it's bound in practice to the Result type(s) defined in std. I'm sure those details are all in the docs somewhere but I spent the time to look yet.
