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

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.
