[I] [Variant] [Shredding] Support typed_access for `Utf8` and `BinaryView` [arrow-rs]
alamb opened a new issue, #8333:
URL: https://github.com/apache/arrow-rs/issues/8333
**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 are implementing Variant support in arrow-rs (🎉 ), and we are currently implementing "shredding" - the ability to read Variants when they have been partially extracted into a type value column.
This ticket tracks adding support for accessing typed values of the type listed in the description of this ticket as a `Variant` value
**Describe the solution you'd like**
Fix the corresponding test cases in the [`shredded_variant`](https://github.com/apache/parquet-testing/tree/master/shredded_variant) test suite.
After https://github.com/apache/arrow-rs/pull/8325 is merged, you can run that suite using:
```shell
cargo test --all-features --test variant_integration
```
**Describe alternatives you've considered**
1. Extend `typed_value_to_variant` for the type ([source link](https://github.com/apache/arrow-rs/blob/aa626e12de8bc0d0f56b5349239cae1be8d1a195/parquet-variant-compute/src/variant_array.rs#L592-L591))
2. Add an appropriate test case, following the models of tests such as
https://github.com/apache/arrow-rs/blob/fb7d02ed0901bb7fff5fd8e27e52ccc4a28b962c/parquet-variant-compute/src/variant_get/mod.rs#L442-L445
