Types

type SectorReader

type SectorReader struct {
	// contains filtered or unexported fields
}

SectorReader is a relatively memory efficient reader to read blocks from a filecoin lotus generated unsealed sector copy.

func NewSectorReader

func NewSectorReader(f io.Reader) (*SectorReader, error)

NewSectorReader creates a new SectorReader instance.

@input - io reader.

@output - sector reader, error.

func (*SectorReader) Advance

func (sr *SectorReader) Advance() error

Advance advances the current pointer to the start of next block.

@output - error.

func (*SectorReader) GetBufPos

func (sr *SectorReader) GetBufPos() uint64

GetBufPos gets the current position of the sub pointer.

@output - position of the sub pointer.

func (*SectorReader) GetPos

func (sr *SectorReader) GetPos() uint64
