Review comment:
@nevi-me I just saw the comment "The JSON can either be an Object or an
Array of Objects" from [ARROW-8883: [Rust] [Integration] Enable more
tests](https://github.com/apache/arrow/commit/18b92818e7e12c6516511abe33b9e9ff78573571#diff-16170ebfd75c15cd0ef92a3e4f35dba353edcb11352101c363fc35cf3729267d)
That's interesting! But I haven't seen the `Object` example from
testing/data/arrow-ipc-stream/integration/1.0.0-littleendian/generated_custom_metadata.json.gz.
So would you please give some pointers?
