Have you tried working with rust-ndarray (the closest thing to NumPy in Rust)? While I love Rust for general work, unfortunately for numeric programming, compared to NumPy itself, it's like pulling teeth. There's a lot which is completely missing: the main thing for me is (boolean) masks, which means there's no element-wise comparison of ndarrays.

It's a cliche for open-source libraries, but ndarray could use more documentation.

A lot more.

A really whole lot more.

"Pulling teeth" is how I'd describe ndarray currently.
