	// GrowthCoeff defines the growth rate of the internal buffer. By
	// default, the growth rate is 1, where expanding the internal
	// buffer will allocate only enough capacity to fit the new expected
	// length.
	GrowthCoeff float64
	// contains filtered or unexported fields
}

A WriteAtBuffer provides a in memory buffer supporting the io.WriterAt interface Can be used with the s3manager.Downloader to download content to a buffer in memory. Safe to use concurrently.

func NewWriteAtBuffer 

func NewWriteAtBuffer(buf []byte) *WriteAtBuffer

NewWriteAtBuffer creates a WriteAtBuffer with an internal buffer provided by buf.

func (*WriteAtBuffer) Bytes 

func (b *WriteAtBuffer) Bytes() []byte

Bytes returns a slice of bytes written to the buffer.

func (*WriteAtBuffer) WriteAt 

func (b *WriteAtBuffer) WriteAt(p []byte, pos int64) (n int, err error)

WriteAt writes a slice of bytes to a buffer starting at the position provided The number of bytes written will be returned, or error. Can overwrite previous written slices if the write ats overlap.
