errors

Documentation

Overview

Package errors is a replacement for the golang standard library "errors". This replacement adds errors to the Open Telemetry spans. The signatures only differs in that New() now takes a context.Context object and fmt.Errorf() has been moved here and also takes a Context.Context.
