3. Please describe how your code solves the related issue.

   Allow column to cast to StructType. Edited generated SQL so that it can rename and add structtype.

We currently do not support RENAME FIELDS or ADD FIELDS in CAST statement and thats why example code in description fail. As I am trying this parameter, RENAME FIELDS only works for structured object and requires them to have the exact same number of fields.
in snowpark design, column is a isolated object that does not have the context of analyzer or the whole generated SQL, which means inside the column we can not know the datatype of it, let alone whether it have exact same number of fields as the datatype it is casting to.
To workaround this, I’ll add parameters in .cast().

please to refer to jira tickets for more detail
