"""

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

0x0002 Bigint

0x0003 Blob

0x0004 Boolean

0x0005 Counter

0x0006 Decimal

0x0007 Double

0x0008 Float

0x0009 Int

0x000A Text

0x000B Timestamp

0x000C Uuid

0x000D Varchar

0x000E Varint

0x000F Timeuuid

0x0010 Inet

0x0011 SimpleDateType

0x0012 TimeType

0x0013 ShortType

0x0014 ByteType

0x0015 DurationType

0x0020 List: the value is an [option], representing the type

of the elements of the list.

0x0021 Map: the value is two [option], representing the types of the

keys and values of the map

0x0022 Set: the value is an [option], representing the type

of the elements of the set
