var Root = func() F {
	return F{[]string{"."}}
}()

Root returns F set to only ".".

var Zero = func() F {
	return F{[]string{}}
}()

Zero returns a zero valued F.

This section is empty.

type F struct {
	Zones []string
}

F can be nil to allow for no fallthrough, empty allow all zones to fallthrough or contain a zone list that is checked.

func (f F) Equal(g F) bool

Equal returns true if f and g are equal.

func (f *F) SetZonesFromArgs(zones []string)

SetZonesFromArgs sets zones in f to the passed value or to "." if the slice is empty.

func (f F) Through(qname string) bool

Through will check if we should fallthrough for qname. Note that we've named the variable in each plugin "Fall", so this then reads Fall.Through().
