Type hints with ellipsis fails to serialize

[sveinse]

Running 32-bit Py 3.8.0 on Win10. desert from master, commit 073a40e

desert does not support types with ellipsis, which is used to indicate a variable length list or tuple with homogeneous types. The following test case:

def test_tuple_ellipsis(module):
    """Test tuple with ellipsis"""

    @module.dataclass
    class A:
        x: t.Tuple[int, ...]

    schema = desert.schema_class(A)()
    dumped = {"x": (1, 2, 3)}
    loaded = A(x=(1, 2, 3))

    assert schema.load(dumped) == loaded
    assert schema.dump(loaded) == dumped
    assert schema.loads(schema.dumps(loaded)) == loaded

Fails on making the schema with:

src\desert\_make.py:107: in class_schema
    raise desert.exceptions.UnknownType(
E   desert.exceptions.UnknownType: Desert failed to infer the field type for Ellipsis.
E   Explicitly pass a Marshmallow field type.

Thanks for the test. This is fixed in v2019.01.04.
