How to annotate Smaller dimension type for PyArray?

[rkshthrmsh]

I am writing a function that accepts a generic PyArray<A, D> and returns a PyArray with dimension D - 1. How should the output of the function type be annotated? Rust ndarray provides a D::Smaller associated type, but I was unable to find an equivalent in PyArray.

The D in PyArray<A, D> just uses the Dimension trait from ndarray, so D::Smaller should work in exactly the same way.

Could you a concrete compiler error you face while trying to use D::Smaller?

You are right. It appears that there was some other issue with my code. Closing this Q&A.
