[Rust] Allow unary kernels of arbitrary array types #26507
Description
Currently, filter support is limited to a set of types, and these types cannot be arbitrarily nested. This hints at a fundamental limitation of the design, that is currently typed (in rust's sense).
However, this operation is fundamentally un-typed: we do not require knowing type information to filter an array.
This issue tracks the development of an abstraction to support these operations for arbitrary types.
