• annotate stacktrace with cause
• grouping errors with errors Code
• custom errors with errors Kind
• mapping errors Code to HTTP/gRPC status code
• does not conflict with the standard errors package name

• localization

Installation

$ go get github.com/alextanhongpin/errors

Usage

There are three subpackage in the errors package, each fulfilling different usecase:

• codes: standard error codes that can be mapped to HTTP/gRPC codes
