Functions

func New

func New(r io.Reader, readerTotalSize uint64) (io.Reader, abi.UnpaddedPieceSize)

New produces a reader that produces the provided reader's bytes with a suffix of NUL bytes.

func NewInflator

func NewInflator(r io.Reader, readerTotalSize uint64, targetSize abi.UnpaddedPieceSize) (io.Reader, error)

NewInflator wraps a reader so that it will return enough bytes to exactly fill the given PieceSize

func PaddedSize

func PaddedSize(size uint64) abi.UnpaddedPieceSize

PaddedSize is an unfortunately-misnamed method: it returns the `unpadded` (payload bearing) size of the smallest piece that could fit the provided `size` payload.
