type Concrete ¶

type Concrete struct {
	Bool     func() bool
	Duration func() time.Duration
	Float    func() float64
	Integer  func() int64
	List     func() []string
	Text     func() string
}

Concrete is a struct of functions that return the concrete values. Only the intended type will return a value, the rest always return zero.

Note there is no meta.Text type because this can be had using the Option.String method below in all cases.

func NewConcrete() Concrete

type Config ¶

type Config map[string]map[string]Option

func (c Config) MarshalText() (b []byte, e error)

type Option ¶

type Option interface {
	FromString(s string) (e error)
	String() (s string)
	Value() (c Concrete)
	Type() (t meta.Type)
	Meta() (md meta.Metadata)
}

Option interface reads and writes string formats for options and returns a Concrete value to the appropriate concrete value, with the type indicated.
