Functions

func CloseLogFile

func CloseLogFile() error

func InitLogFile

func InitLogFile() error

func NewContext

func NewContext(ctx context.Context, logger *Logger) context.Context

NewContext derives a context that carries logger from ctx.

Types

type Level

type Level int

const (
	Debug Level = iota
	Info
	Warn
	Error

	NoLogLevel = -1
)

type Logger

type Logger struct {
	// contains filtered or unexported fields
}
