Thanks through I still don't get it. I only know that you can get backtraces of errors by setting `RUST_BACKTRACE=1`.

  That only gives you backtraces for panics, but not for errors based on the Result<,> type.

    I am not serious. Often in these cases I would use printf debugging to know where the errors came. (I am still a Rust beginner).
