[I] Plans for supporting Extension Array to support Fixed shape tensor Array [arrow-rs]

haixuanTao opened a new issue, #4890:
URL: https://github.com/apache/arrow-rs/issues/4890

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   Currently, there is no way easy way to support tensor data, which could be handy to do things like AI. And it seems that there is no tracking issue.
   
   See: https://arrow.apache.org/docs/format/CanonicalExtensions.html
   And example python implementation:
   See: https://arrow.apache.org/docs/python/generated/pyarrow.ExtensionArray.html
    
   **Describe the solution you'd like**
   Implementation should be pretty straightforward as there already a Tensor Primitive Type.
   
   **Additional context**

   For anyone else who (like me) stumbles across this issue: `FixedShapeTensor`, and the other canonical extension types, were merged into `arrow-rs` in version 54.1.0  (Feb 2025).
   
   - [Docs for `FixedShapeTensor`](https://arrow.apache.org/rust/arrow_schema/extension/canonical/fixed_shape_tensor/struct.FixedShapeTensor.html)
   - PR #5822
