func (*Range) Canonicalize ¶

func (r *Range) Canonicalize() error

Canonicalize takes a given range and ensures that all information is consistent, filling out Start, End, and Gateway with sane values if missing

func (*Range) Contains ¶

func (r *Range) Contains(addr net.IP) bool

Contains checks if a given ip contained in the range

func (*Range) Overlaps ¶

func (r *Range) Overlaps(r1 *Range) bool

Overlaps returns true if there is any overlap between ranges

func (*Range) String ¶

func (r *Range) String() string

String prints the range

func (*RangeIter) Next ¶

func (i *RangeIter) Next() (*net.IPNet, net.IP)

Next returns the next IP, its mask, and its gateway. Returns nil if the iterator has been exhausted

func (*RangeSet) Canonicalize ¶

func (rs *RangeSet) Canonicalize() error

Canonicalize ensures the RangeSet is in a standard form, and detects any invalid input. Call Range.Canonicalize() on every Range in the set

func (*RangeSet) Concat ¶

func (rs *RangeSet) Concat(s string, subnet *net.IPNet) (*RangeSet, error)

Concat concats RangeSet from string for given subnet. eg: "10.0.0.[2-4], 10.0.1.4, 10.0.1.5, 10.0.1.9", 10.0.1.0/24

func (*RangeSet) Contains ¶

func (rs *RangeSet) Contains(addr net.IP) bool

Contains returns true if any range in this set contains an IP

func (RangeSet) Len ¶

func (rs RangeSet) Len() int

func (RangeSet) Less ¶

func (rs RangeSet) Less(i, j int) bool

func (*RangeSet) Overlaps ¶

func (rs *RangeSet) Overlaps(p1 *RangeSet) bool

Overlaps returns true if any ranges in any set overlap with this one

func (*RangeSet) RangeFor ¶

func (rs *RangeSet) RangeFor(addr net.IP) (*Range, error)

RangeFor finds the range that contains an IP, or nil if not found

func (*RangeSet) String ¶

func (rs *RangeSet) String() string

func (RangeSet) Swap ¶

func (rs RangeSet) Swap(i, j int)
