[jira] [Created] (ARROW-10540) [Rust] Allow unary kernels of arbitrary types

Jorge Leitão created ARROW-10540:
------------------------------------

             Summary: [Rust] Allow unary kernels of arbitrary types
                 Key: ARROW-10540
                 URL: https://issues.apache.org/jira/browse/ARROW-10540
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust
            Reporter: Jorge Leitão
            Assignee: Jorge Leitão


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.
