Python

Minimal reproduce step

1. Run the Java test case testEnumField in org.apache.fury.CrossLanguageTest

2. The test attempts to execute the Python counterpart using:

python -m pyfury.tests.test_cross_language test_enum_field [path]

3. The Java side fails with an assertion error, and the Python side fails with an AttributeError.

What did you expect to see?

The cross-language enum field serialization test should pass successfully, with the Java side correctly validating that the serialized data matches the expected result.

What did you see instead?

1. Java test failure:

[ERROR] testEnumField(org.apache.fury.CrossLanguageTest)  Time elapsed: 0.655 s  <<< FAILURE!
java.lang.AssertionError: expected [true] but found [false]
	at org.apache.fury.CrossLanguageTest.structRoundBack(CrossLanguageTest.java:534)
	at org.apache.fury.CrossLanguageTest.testEnumField(CrossLanguageTest.java:793)

2. Python error:

AttributeError: 'pyfury._serialization.ClassInfo' object has no attribute 'namespace'

The error occurs in the Python deserializer when processing enum fields. The specific error path is:

File "D:\projects\fury_dev\fury\python\pyfury\_struct.py", line 263, in visit_customized
    classinfo.namespace + classinfo.typename
    ^^^^^^^^^^^^^^^^^^^
AttributeError: 'pyfury._serialization.ClassInfo' object has no attribute 'namespace'

This suggests that the ClassInfo object in the Python implementation is missing the namespace attribute that is being referenced in the code, causing cross-language enum field serialization to fail.

Anything Else?
