Types

type Field

type Field = zapcore.Field

type KratosLogger

type KratosLogger interface {
	// Log implements is used to github.com/go-kratos/kratos/v2/log.Logger interface.
	Log(level krtlog.Level, keyvals ...any) error
}

type Logger

type Logger interface {
	Debugf(format string, args ...any)
	Debugw(msg string, keyvals ...any)
	Infof(format string, args ...any)
	Infow(msg string, keyvals ...any)
	Warnf(format string, args ...any)
	Warnw(msg string, keyvals ...any)
	Errorf(format string, args ...any)
	Errorw(err error, msg string, keyvals ...any)
