Config for zerolog logger

func (*Config) Repair

func (c *Config) Repair()

Repair errors

type Event

type Event = zerolog.Event

Event represents a log event. It is instanced by one of the level method of Logger and finalized by the Msg or Msgf method.

type Hook

type Hook func(b []byte)

func (Hook) Write

func (h Hook) Write(b []byte) (n int, err error)

type Level

type Level = zerolog.Level

Level defines log levels.

type Logger

type Logger = zerolog.Logger

A Logger represents an active logging object that generates lines of JSON output to an io.Writer. Each logging operation makes a single call to the Writer's Write method. There is no guarantee on access serialization to the Writer. If your Writer is not thread safe, you may consider a sync wrapper.

func New

func New(conf Config, hook Hook) Logger

New logger with config

func Nop

func Nop() Logger

Nop returns a disabled logger for which all operation are no-op.
