The `color-backtrace` crate provides colorized, richly formatted backtraces when crashes occur: https://github.com/athre0z/color-backtrace When built with debug symbols, it's also capable of displaying the relevant source code for each stack frame in the backtrace. With `default-features = false`, it's nicely parsimonious with our existing dependencencies, and only adds a single additional transitive dependency, `atty` (which we previously used, and should potentially consider using again).
