func Wrap

func Wrap(message string, err error) error

Wrap is a simple wrapper around Errorf that is doing error wrapping. You can read how that works in https://godoc.org/golang.org/x/xerrors#Errorf but its API is very implicit which is a reason for this wrapper. There is also a discussion (https://github.com/golang/go/issues/29934) where many comments make arguments for such wrapper so hopefully it will be added in the standard lib later.

func Wrapf

func Wrapf(err error, message string, a ...interface{}) error

Wrapf is a simple wrapper around Errorf that is doing error wrapping Wrapf allows you to send a format and args instead of just a message.
