I do not know about the "best" way and I do not have the time to test it, but a quick search returns

• Fastest way of converting between OpenCV Mat and Rust ndarray (or other Rust arrays)? Or even better, zero-copy? twistedfall/opencv-rust#267
• https://github.com/jerry73204/rust-cv-convert/blob/master/cv-convert/src/with_opencv_ndarray.rs

You're free to test it.
