Package errors provides simple error handling primitives, compatible with Go 1.13 error wrapping.
go get github.com/objenious/errors
The traditional error handling idiom in Go is roughly akin to
if err != nil {
return err
}which applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error.
The errors.Wrap function returns a new error that adds context to the original error. For example
_, err := ioutil.ReadAll(r)
if err != nil {
return errors.Wrap(err, "read failed")
