class Pyper::Pipes::Cassandra::PaginationDecoding

This pipe extracts an encoded paging_state, decodes it, and passes on a decoded paging state. This pipe is intended to be used before the Cassandra::Reader pipe, as that pipe can interpret the :paging_state argument.

This pipe pairs with the PaginationEncoding pipe, which performs the reverse transformation
