anyhowcrate is a gem within the Rust ecosystem. Let’s see how it works! The default error messages provided by the
Result::Errtype are quite spartan.
anyhowprovides the ability to annotate errors with context messages with its
Contexttrait, which can provide more informative error messages and thus shorten the debugging process. It’s much simpler than wading through messages printed to the console. This short video introduces the crate with a simple example.
