Functions

func IterateBitMasks

func IterateBitMasks(bits []int, callback func(BitMask))

IterateBitMasks iterates all possible masks from a list of bits, issuing a callback on each mask.

BitMask interface allows hint providers to create BitMasks for TopologyHints

func And

func And(first BitMask, masks ...BitMask) BitMask

And is a package level implementation of 'and' between first and masks

func NewBitMask

func NewBitMask(bits ...int) (BitMask, error)

NewBitMask creates a new BitMask

func NewEmptyBitMask

func NewEmptyBitMask() BitMask

NewEmptyBitMask creates a new, empty BitMask

func Or

func Or(first BitMask, masks ...BitMask) BitMask

Or is a package level implementation of 'or' between first and masks
