Why is zerror made

I want errors to be clearly organized and reusable and classified in groups

I want hide errors from client and return code instead

I want to respond predefined code and log error in one line code

I want to respond with different Status Code for Grpc/Http for error generated/wrapped by zerror

so Zerror is here
