// Package internal of logger unifies different types of loggers into
// interfaces Logger. For example it allows to upgrade simple fmt.Printf
// to be a fully functional Logger. Therefore multiple wrappers are implemented
// here to provide different functions which could be missing in some loggers.
package internal

// MinimalLoggerLogf is an implementation of method Logf (of interface
// MinimalLoggerCompact) based on MinimalLogger.
//
// This function is implemented here to deduplicate code among logadapter-s.
