Initializes logging.

Logging should be used for Python and sync Rust logic which is most of the components in the nautilus_trader package. Logging can be configured to filter components and write up to a specific level only by passing a configuration using the NAUTILUS_LOG environment variable.

Safety

Should only be called once during an application’s run, ideally at the beginning of the run.

This function assumes:

• directory_ptr is either NULL or a valid C string pointer.
• file_name_ptr is either NULL or a valid C string pointer.
• file_format_ptr is either NULL or a valid C string pointer.
• component_level_ptr is either NULL or a valid C string pointer.

Panics

Panics if initializing the Rust logger fails.
