Functions ¶

func IsValidLabel ¶

func IsValidLabel(name string) bool

IsValidLabel returns true if the string given is a valid DNS label (RFC 1123). Note: the only difference between RFC 1035 and RFC 1123 labels is that in RFC 1123 labels can begin with a number.

func ValidateLabel ¶

func ValidateLabel(name string) error

ValidateLabel is similar to IsValidLabel except it returns an error instead of false when name is not a valid DNS label. The error will contain reference to what constitutes a valid DNS label.

Types ¶

type RecursorStrategy ¶

type RecursorStrategy string

const (
	RecursorStrategySequential RecursorStrategy = "sequential"
	RecursorStrategyRandom     RecursorStrategy = "random"
)

func (RecursorStrategy) Indexes ¶

func (s RecursorStrategy) Indexes(max int) []int
