Functions

func ToByteReader

func ToByteReader(r io.Reader) io.ByteReader

func ToReaderAt

func ToReaderAt(rs io.ReadSeeker) io.ReaderAt

Types

type ByteReadSeeker

type ByteReadSeeker interface {
	io.ReadSeeker
	io.ByteReader
}

func ToByteReadSeeker

func ToByteReadSeeker(r io.Reader) ByteReadSeeker

type OffsetWriteSeeker

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

func NewOffsetWriter

func NewOffsetWriter(w io.WriterAt, off int64) *OffsetWriteSeeker

func (*OffsetWriteSeeker) Position

func (ow *OffsetWriteSeeker) Position() int64

Position returns the current position of this writer relative to the initial offset, i.e. the number of bytes written.

func (*OffsetWriteSeeker) Seek

func (ow *OffsetWriteSeeker) Seek(offset int64, whence int) (int64, error)

func (*OffsetWriteSeeker) Write

func (ow *OffsetWriteSeeker) Write(b []byte) (n int, err error)

type ReadSeekerAt

type ReadSeekerAt interface {
	io.Reader
	io.ReaderAt
	io.Seeker
	io.ByteReader
}

func NewOffsetReadSeeker

func NewOffsetReadSeeker(r io.ReaderAt, off int64) (ReadSeekerAt, error)

NewOffsetReadSeeker returns an ReadSeekerAt that reads from r starting offset offset off and stops with io.EOF when r reaches its end. The Seek function will panic if whence io.SeekEnd is passed.
