Functions

func Debugf

func Debugf(format string, args ...interface{})

Types

type Configuration

type Configuration struct {
	EnableConsole     bool
	ConsoleJSONFormat bool
	ConsoleLevel      string
	EnableFile        bool
	FileJSONFormat    bool
	FileLevel         string
	FileLocation      string
}

Configuration stores the config for the logger For some loggers there can only be one level across writers, for such the level of Console is picked by default

type Fields

type Fields map[string]interface{}

Fields Type to pass when we want to call WithFields for structured logging

type Logger

type Logger interface {
	Debugf(format string, args ...interface{})

	Infof(format string, args ...interface{})

	Warnf(format string, args ...interface{})

	Errorf(format string, args ...interface{})

	Fatalf(format string, args ...interface{})

	Panicf(format string, args ...interface{})

	WithFields(keyValues Fields) Logger
}

Logger is our contract for the logger

func WithFields

func WithFields(keyValues Fields) Logger
