StreamTokenBinaryReader¶

class dsviper.StreamTokenBinaryReader(stream_raw_reading)¶

Bases: object

Reads a portable binary stream that carries a type token per value.

Each read checks the token before decoding, so reading a value as another type fails at that value instead of returning nonsense. The token names a type only: corrupted bytes inside a value of the right type still read. Larger and slower than StreamBinary.
