Did you check the errors package: https://godoc.org/github.com/pkg/errors ?
It offers a great way to wrap chained errors.

Is there a idiomatic recommendation for generally displaying errors resulting
from chained methods?
The following would print out "ERROR: Foo() ERROR: Bar() ERROR: stdlib.Func()
something went wrong with this standard function call", which feels obviously
wrong.
func main() {
if err := Foo(); err != nil {
fmt.Printf("ERROR: Foo() %s", err)
os.Exit(1)
}
}
func Foo() error {
if err := Bar(); err {
return fmt.Errorf("ERROR: Bar() %s", err)
}
return nil
}
func Bar() error {
if err := stdlib.Func(); err != nil {
return fmt.Errorf("ERROR: stdlib.Func() %s", err)
}
return nil
}
