  • func New(r string) (*RangeSpec, error)
  • func (rs *RangeSpec) InRange(num uint64) bool

Types

type RangeSpec

type RangeSpec struct {
	Max uint64
	// contains filtered or unexported fields
}

RangeSpec parses a range specification, such as: 1,3,5-8,12- It will return a slice of RangeSpec, being two ints, a start and a stop Ranges start at 1, not zero.

func New

func New(r string) (*RangeSpec, error)

New takes a range specification string and returns a slice of RangeSpec structs

func (*RangeSpec) InRange

func (rs *RangeSpec) InRange(num uint64) bool

InRange will test whehter a number is in the range specification
