Description

descrition of params chunks does not correspond to what gives me a console.log

[
  {
    chunk: <Buffer ff ff>,
    encoding: 'buffer',
    callback: [Function: nop],
    next: {
      chunk: <Buffer ff ff>,
      encoding: 'buffer',
      callback: [Function: nop],
      next: [Object]
    }
  },
  {
    chunk: <Buffer ff ff>,
    encoding: 'buffer',
    callback: [Function: nop],
    next: {
      chunk: <Buffer ff ff>,
      encoding: 'buffer',
      callback: [Function: nop],
      next: [Object]
    }
  },
  {
    chunk: <Buffer ff ff>,
    encoding: 'buffer',
    callback: [Function: nop],
    next: {
      chunk: <Buffer ff ff>,
      encoding: 'buffer',
      callback: [Function: nop],
      next: null
    }
  },
  {
    chunk: <Buffer ff ff>,
    encoding: 'buffer',
    callback: [Function: nop],
    next: null
  },
  allBuffers: true
]

I can call callback in chunks object? or call callback in 2nd parameter?
What is allBuffers?

thank you for taking the time to read my request (:

I am not the author but here is my explanation: chunk and encoding are documented and should be used. the rest is not documented and therefore should not be used. It is an implementation detail.

@codati - can you share your code please? I am not able to see the additional fields which you shared.
