Francesco Guardiani updated FLINK-24462:
----------------------------------------
Description: The goal of this issue is to reorganize CAST logic in rules,
similarly to DataStructureConverter. This makes the casting rules easier to
debug and extend, allows us to reuse some of the rules for
https://issues.apache.org/jira/browse/FLINK-21456 without duplicating any code
and simplifies/cleanups the code generator code base. These rules can be reused
in the context of https://issues.apache.org/jira/browse/FLINK-24385 as well.
