**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** - part of https://github.com/apache/arrow-rs/issues/6736 We introduced the basic `variant_get` kernel in and now we need to expand its feature set - https://github.com/apache/arrow-rs/pull/8021 In particular, Shredded Arrays (VariantList) are described here: * [Representing Variant In Arrow Proposal: "Shredding an Array"](https://docs.google.com/document/d/1pw0AWoMQY3SjD7R4LgbPvMjG_xSCtXp3rZHkVp9jpZ4/edit?tab=t.0#heading=h.z9168wdrn689) * [Variant Shredding::Arrays](https://github.com/apache/parquet-format/blob/master/VariantShredding.md#arrays) **Describe the solution you'd like** I would like `variant_get` to support shredded arrays, along with being able to extract elements from them. So roughly that means ```rust // get the variant as a ListArray variant_get(array, Field::new(List...))) // get the shredded variant as a non shredded variant (convert to Variant::List) variant_get(array) ``` **Describe alternatives you've considered** 1. Add a test that manually constructs a shredded variant array (follow the example in the arrow proposal) 2. Add a test that tries to get that array as a variant and as a ListArray 3. Implement the code **Additional context** Reference - [Variant Spec](https://github.com/apache/parquet-format/blob/master/VariantEncoding.md#encoding-types) - [Variant Shredding Spec](https://github.com/apache/parquet-format/blob/master/VariantShredding.md#value-shredding) - [Representing Variant In Arrow Proposal](https://docs.google.com/document/d/1pw0AWoMQY3SjD7R4LgbPvMjG_xSCtXp3rZHkVp9jpZ4) -- This is an automated message from the Apache Git Service.
