+/// Cast a struct array to another struct type by aligning child arrays using
+/// field names instead of their physical order.
+///
+/// This is a convenience wrapper around the internal function
`cast_struct_column` that accepts
+/// `Fields` directly instead of requiring a `Field` wrapper.
+///
+/// See [`cast_column`] for detailed documentation on the casting behavior.
+///
+/// # Arguments
+/// * `array` - The source array to cast (must be a struct array)
+/// * `target_fields` - The target struct field definitions
+/// * `cast_options` - Options controlling cast behavior (strictness,
formatting)
+///
+/// # Returns
+/// A `Result<ArrayRef>` containing the cast struct array
+///
+/// # Errors
+/// Returns an error if the source is not a struct array or if field casting
fails
