Function ErrorOutput

options.go:75–79

ErrorOutput sets the destination for errors generated by the Logger. Note that this option only affects internal errors; for sample code that sends error-level logs to a different location from info- and debug-level logs, see the package-level AdvancedConfiguration example. The supplied WriteSyncer

(w zapcore.WriteSyncer)

// The supplied WriteSyncer must be safe for concurrent use. The Open and
// zapcore.Lock functions are the simplest ways to protect files with a mutex.
func ErrorOutput(w zapcore.WriteSyncer) Option {
	return optionFunc(func(log *Logger) {
		log.errorOutput = w
	})
}

// Development puts the logger in development mode, which makes DPanic-level
// logs panic instead of simply logging an error.
