    This namespace provides methods for operating on struct-typed columns using
    PyArrow compute functions.

    Example:
        >>> from xpark.dataset.expressions import col
        >>> # Access a field using method
        >>> expr = col("user_record").struct.field("age")
        >>> # Access a field using bracket notation
        >>> expr = col("user_record").struct["age"]
        >>> # Access nested field
        >>> expr = col("user_record").struct["address"].struct["city"]
