Types

type Config

type Config struct {
	Level  *Level `yaml:"level" required:"true" default:"info"`
	Output string `yaml:"output" default:"stdout"`
}

Config represents a logging config.

func (*Config) LogLevel

func (m *Config) LogLevel() Level

type Level

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

Level represents a shifted zap logging level that is able to being constructed from YAML.

func NewLevel

func NewLevel(level zapcore.Level) *Level

func NewLevelFromString

func NewLevelFromString(level string) (*Level, error)

func (Level) MarshalText

func (m Level) MarshalText() (text []byte, err error)

func (*Level) UnmarshalYAML

func (m *Level) UnmarshalYAML(unmarshal func(interface{}) error) error

func (Level) Zap

func (m Level) Zap() zapcore.Level

Zap returns the underlying zap logging level.

type Leveler

type Leveler interface {
	// LogLevel return log verbosity.
	LogLevel() Level
}
