Types

type BitField

type BitField = bitfield.BitField

type BitfieldQueue

type BitfieldQueue struct {
	*adt.Array
	// contains filtered or unexported fields

func LoadBitfieldQueue

func LoadBitfieldQueue(store adt.Store, root cid.Cid, quant builtin.QuantSpec, bitwidth int) (BitfieldQueue, error)

func (BitfieldQueue) ForEach

func (q BitfieldQueue) ForEach(cb func(epoch abi.ChainEpoch, bf bitfield.BitField) error) error
