A famous cheminformatics library in Python, RDKit, has functions to generate conformers for molecules, such as ETKDGv2. Where on earth does the source file exist?

I found the file: Parameter definition: Embedder.cpp Based on the source, as I cannot read C++, it is inferred that ETKDGv2 or other functions are defined as a function and parameters. Therefore, ETKDGv2 and other methods are found in separate functions. I have found another clue: Interface for Python

In short note, ETKDGv2 and other functions are compiled by Cython from the C++ source code.
