Use the failure crate to handle errors.
- The failure crate is a young error handling solution for Rust. It
may change the API, but since we pin our dependencies, this should
not be a problem for us, albeit a bit inconvenient.
- Introduction of the crate is a bit noisy, but not as bad as
anticipated, because failure magically handles all errors used in
the standard library.
- Matching on concrete error values requires downcasting before
matching, which seems a bit unidiomatic. This is the cost of
using and "chaining" arbitrary error types. This is something
that may be improved later on in the library or language.
- Having said that, using the error type in the tool was nice. I
did not have to use a downcast, so maybe my worries about
downcasts are unjustified because it is not such a common use case
after all. On the other hand, the tool is quite simple and our
only mode of failure is to print the message.
