30/// The module is exposed under different paths depending on the build configuration:
31/// - With `cython-compat` feature: `nautilus_trader.core.nautilus_pyo3.databento`
32/// - Without `cython-compat`: `nautilus_trader.databento` (via re-export)

34/// # Errors
35///
36/// Returns a `PyErr` if registering any module components fails.
