Types

type Config

type Config struct {
	SyncPeriod time.Duration `yaml:"sync_period"`
	Stdin      bool          `yaml:"stdin"`
}

Config describes behavior for Target

func (*Config) RegisterFlags

func (cfg *Config) RegisterFlags(flags *flag.FlagSet)

RegisterFlags register flags.

func (*Config) RegisterFlagsWithPrefix

func (cfg *Config) RegisterFlagsWithPrefix(prefix string, f *flag.FlagSet)

RegisterFlags with prefix registers flags where every name is prefixed by prefix. If prefix is a non-empty string, prefix should end with a period.

type FileTarget

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

FileTarget describes a particular set of logs. nolint:revive
