Types

type Factory

type Factory func(pkgName string) ILogger

Factory is the factory method for creating logger used for the specified package.

type ILogger

type ILogger interface {
	SetLevel(LogLevel)
	Debugf(format string, args ...interface{})
	Infof(format string, args ...interface{})
	Warningf(format string, args ...interface{})
	Errorf(format string, args ...interface{})
	Panicf(format string, args ...interface{})
}

ILogger is the interface implemented by loggers that can be used by dragonboat. You can implement your own ILogger implementation by building wrapper struct on top of your favourite logging library.

func CreateCapnsLog

func CreateCapnsLog(pkgName string) ILogger

CreateCapnsLog creates an ILogger instance based on capnslog.

func GetLogger

GetLogger returns the logger for the specified package name. The most common use case for the returned logger is to set its log verbosity level.

type LogLevel

type LogLevel int

LogLevel is the log level defined in dragonboat.

const (
	// CRITICAL is the CRITICAL log level.
	CRITICAL LogLevel = iota - 1
	// ERROR is the ERROR log level.
