type_codes.py

"""
Module with constants for Cassandra type codes.

These constants are useful for

    a) mapping messages to cqltypes                (cassandra/cqltypes.py)
    b) optimized dispatching for (de)serialization (cassandra/encoding.py)

Type codes are repeated here from the Cassandra binary protocol specification:

            0x0000    Custom: the value is a [string], see above.
            0x0001    Ascii
