Disk Buffer Reader

Are you tired of dealing with how to use a reader more than once? Me too! Rather than teeing a reader, reading it all, or other messy methods, try using your disk!

What it does

Disk buffer reader uses takes everything read from a reader, writes it to a temporary file on disk, and resets the reader to read from the start again. Once you're done reusing your reader, stop the recording function and use it as normal.

Example

func main() {
  readerOriginal := bytes.NewBuffer([]bytes("OneTwoThr")
  dbr, _ := diskBufferReader.NewReader(readerOriginal)
  defer dbr.Close() // Close reader and delete tmp file.
  message := make([]byte, 3)
  for i := 0; i < 3; i++ {
    dbr.Read(message)
    fmt.Println(message)
  }
  for i := 0; i < 3; i++ {
    dbr.Reset() // Reset reader to 0.
    dbr.Read(message)
    fmt.Println(message)
  }
  dbr.Stop() // Stop storing read bytes in tmp file.
}
