Thanks for suggesting an improvement to error reporting! But I'm confused by this change. .with_context is supposed to add context to the error, not replace it. So the message in e.to_string() should already be available from the returned error. See the documentation on anyhow::Context.

I suspect if you didn't see the "Caused by:" chain in the error output, then the root issue here is that something is not printing errors in the right way. Can you provide more information about what you tried and what output you got?

@jameysharp you are right, thank you! That was not obvious to me. Sorry for rubberducking you instead of reading the docs >..<

For the context (pun intended), anyhow::Context prints only context part of error using Display printer {}. In order to print full info, including "source", {:#} should be used.
