type ChunkedReader struct {

}
ChunkedReader is a reader for an Object with the possibility of reading the source in chunks of given size
An initialChunkSize of <= 0 will disable chunked reading.
func New(ctx context.Context, o fs.Object, initialChunkSize int64, maxChunkSize int64) *ChunkedReader
New returns a ChunkedReader for the Object.
An initialChunkSize of <= 0 will disable chunked reading. If maxChunkSize is greater than initialChunkSize, the chunk size will be doubled after each chunk read with a maximum of maxChunkSize. A Seek or RangeSeek will reset the chunk size to it's initial value
func (cr *ChunkedReader) Close() error
Close the file - for details see io.Closer
All methods on ChunkedReader will return ErrorFileClosed afterwards
func (cr *ChunkedReader) Open() (*ChunkedReader, error)
Open forces the connection to be opened
func (cr *ChunkedReader) RangeSeek(ctx context.Context, offset int64, whence int, length int64) (int64, error)
RangeSeek the file - for details see RangeSeeker
The specified length will only apply to the next chunk opened. RangeSeek will not reopen the source until Read is called.
func (cr *ChunkedReader) Read(p []byte) (n int, err error)
Read from the file - for details see io.Reader
Seek the file - for details see io.Seeker
