Where you found this expect() function and how it will receive error, generated by baz? I read Rust documentation about error handling multiple times, but newer saw adequate error handling.
The best solution I know is error-chain library:
use errors::ChainErr;
try!(do_something().chain_err(|| "Something went wrong"));

[templates.rs:125] ERROR: Cannot process template "header". Check is template file exists and readable. [fileio.rs:45] ERROR: Cannot open file "/usr/share/foo/templates/header.tmpl": unable to enter directory "/usr/share/foo". Check directory permissions. Instead of writing report cannot open file done It saves lot of time(money) in production.
