A convinience-wrapper arround protocol-buffers and lp-messages functions

API

• wrap(duplex, opts): Wraps a duplex, returns below object (opts=Object with encode/decode opts from it-length-prefixed api)
  • .read(bytes): async, reads the given amount of bytes
  • .readLP(): async, reads one length-prefixed message
  • .readPB(proto): async, reads one protocol-buffers length-prefixed message (proto=Object with .encode, .decode functions)
  • .write(data): writes the given data (data=Buffer or BufferList)
  • .writeLP(data): writes the given data with a length-prefixe (data=Buffer or BufferList)
  • .writePB(data, proto): encodes the data, then writes it withg a length-prefix (data=Buffer or BufferList, proto=Object with .encode, .decode functions)
  • .pb(proto): returns a convinience wrapper for writing messages
    • .read(): reads one length-prefixed message encoded with proto
    • .write(data): writes one length-prefixed message encoded with proto
