How to return error with message or there is a better way? #15892
Description
Based on my previous programming experience, it's common that I define a set of error codes and errors are constructed with a code with a detailed message.
It seems Zig provides error set enums to fit the error code part, while I don't know how to return errors with messages. Or it's Zig's best practice to representing errors fully by codes.
A real-world example is that - when I'm parsing a specific config file, I'd like to distinguish parsing errors and IO errors, but what exactly the parsing error is is not significant. While I still need to tell the caller about the details of the parsing error, the control flow is the same for all of them.
