Thanks for this post. It’s been a while since I wrote a lot of rust code that needed more error handling. I used the error-chain crate like two years ago and was never really satisfied. The macro construct felt weird. I also split my application into binary and library part. I will check out these two crates for my next project because the code looked really nice. Except maybe the map_err cases. I dislike the need to manually wrap errors around. The error-chain crate had default into implementations and chain functions for the result type. But honestly I never got around to understand when to use what. [error-chain]: https://crates.io/crates/error-chain https://crates.io/crates/error-chain
