A simple buffer that is optionally backed by a concrete file on disk when it grows too large.

)

func main() {
  r := strings.NewReader("foobar")
  
  buf := mem_constrained_buffer.NewDefaultMemoryConstrainedBuffer()
  defer buf.Close()  // removes any temp files
  
  if _, err := buf.ReadFrom(r); err != nil {
    panic(err)
  }
  
  fmt.Printf("Read %d bytes", buf.Len())
}
