logrus wrapper for standard go log.Logger

Question

I have a struct requesting a standard log.Logger as parameter for log messages. From the zap logger a wrapper is provided by NewStdLogAt:

stdLogAt, err := zap.NewStdLogAt(&s.log, zap.ErrorLevel)

Now I have to use this module in a logrus logger environment. I have not found logrus providing an implementation for log.Logger. What are my possible approaches? Is there an implementation available?

Well, since I have not found a solution I have no code. I added the zap approach. — k_o_, May 19 '23 at 20:50

The Logrus documentation seems to suggest creating a new log.Logger using the result of the Writer function which Logrus loggers and entries provide.

w := logrusLogger.Writer()

// or to define an error level:
// logrusLogger.WriterLevel(logrus.ErrorLevel)

// note that you are responsible for closing the writer
defer w.Close() 

stdlibLogger := log.New(w, "", 0)

I have inferred this from the "Logger as an io.Writer" section on this page.
