Types

type LogFormat

type LogFormat int

const (
	LogFormatText LogFormat = iota
	LogFormatJSON
)

func ParseLogFormat

func ParseLogFormat(f string) LogFormat

type LogLevel

type LogLevel int

const (
	LevelInfo LogLevel = iota
	LevelDebug
	LevelError
	LevelWarn
	LevelFatal
)

type LogOptions

type LogOptions struct {
	// FileLogging specifies whether logs should be additionally written to a file
	// FileLoggingJSON specifies whether log lines to files should be JSON formatted
	FileLoggingJSON bool
	// ConsoleLoggingJSON specifies whether log lines written to the console should be JSON formatted
	ConsoleLoggingJSON bool
	// LogLevel specifies the log level to be used
	LogLevel LogLevel
	// LogSpy can be used as an additional log sink to capture the logs
	LogSpy io.Writer
	// LogTimeMode specifies which time mode shall be used when printing out logs
	LogTimeMode LogTimeMode

	File afero.File

LogOptions holds different options that can be passed to setup the logger to change its behavior

	Warn(msg string, args ...interface{})
	Fatal(msg string, args ...interface{})
	WithFields(fields ...field.Field) Logger
	Level() LogLevel
}

Logger defines the interface for a logging implementation
