Functions

func PieceRun

func PieceRun(offset storiface.PaddedByteIndex, size abi.PaddedPieceSize) rlepluslazy.RunIterator

Types

type PartialFile

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

func CreatePartialFile

func CreatePartialFile(maxPieceSize abi.PaddedPieceSize, path string) (*PartialFile, error)

func OpenPartialFile

func OpenPartialFile(maxPieceSize abi.PaddedPieceSize, path string) (*PartialFile, error)

func (*PartialFile) Allocated

func (pf *PartialFile) Allocated() (rlepluslazy.RunIterator, error)

func (*PartialFile) Close

func (pf *PartialFile) Close() error

func (*PartialFile) Free

func (pf *PartialFile) Free(offset storiface.PaddedByteIndex, size abi.PaddedPieceSize) error

func (*PartialFile) HasAllocated

func (pf *PartialFile) HasAllocated(offset storiface.UnpaddedByteIndex, size abi.UnpaddedPieceSize) (bool, error)

func (*PartialFile) MarkAllocated

func (pf *PartialFile) MarkAllocated(offset storiface.PaddedByteIndex, size abi.PaddedPieceSize) error

func (*PartialFile) Reader

func (pf *PartialFile) Reader(offset storiface.PaddedByteIndex, size abi.PaddedPieceSize) (io.Reader, error)

Reader forks off a new reader from the underlying file, and returns a reader starting at the given offset and reading the given size. Safe for concurrent use.

func (*PartialFile) Writer

func (pf *PartialFile) Writer(offset storiface.PaddedByteIndex, size abi.PaddedPieceSize) (io.Writer, error)
