    """ArrowType enumerator

    This enum makes the type identifier constants available to Cython and
    Python code as (e.g.) ``_types.UNINITIALIZED``. This removes the need
    for other modules to import type codes, which in previous versions had
    led to very long ``from nanoarrow_c cimport`` declarations.
