 /**
  * Basic input stream which supplies binary data.
  *
  * Input streams are used to read data sequentially from some data
  * source. All input streams are non-blocking. They each have a number
  * of read calls which will always return without any IO related
  * blocking. If the requested data is not available a read call will
  * return `null`. All input streams have one or more handlers which
  * will trigger when data is available.
