Types

type Calculator

type Calculator struct {
	IPv4Pools             *iradix.Tree
	AllocatedIPv4Prefixes *iradix.Tree
	IPv6Pools             *iradix.Tree
	AllocatedIPv6Prefixes *iradix.Tree
}

Calculator stores radix trees of supernets and subnets.

func NewCalculator

func NewCalculator() *Calculator

NewCalculator creates a new Calculator from a list of supernets and subnets.

func (*Calculator) AddAllocatedPrefix

func (c *Calculator) AddAllocatedPrefix(prefix netip.Prefix)

func (*Calculator) AddPool

func (c *Calculator) AddPool(prefix netip.Prefix)

func (*Calculator) DeleteAllocatedPrefix

func (c *Calculator) DeleteAllocatedPrefix(prefix netip.Prefix)

func (*Calculator) DeletePool

func (c *Calculator) DeletePool(prefix netip.Prefix)

func (*Calculator) NextAvailableIPv4Subnet

func (c *Calculator) NextAvailableIPv4Subnet(numBits int) (netip.Prefix, error)

NextAvailableIPv4Subnet finds the first available IPv4 subnet of a given mask length from a list of subnets and supernets, and fails if none are available.

func (*Calculator) NextAvailableIPv6Subnet

func (c *Calculator) NextAvailableIPv6Subnet(numBits int) (netip.Prefix, error)

NextAvailableIPv6Subnet finds the first available IPv6 subnet of a given mask length from a list of subnets and supernets, and fails if none are available.

func (*Calculator) PrefixInPools

func (c *Calculator) PrefixInPools(prefix netip.Prefix) bool

PrefixInPools tests to see if a prefix is a part of any pools that have been added to the calculator.
