casting Dict(_, LargeUtf8) to Utf8View (StringViewArray) panics #9101
Description
Describe the bug
I tried to unpack a dict in a memory-efficient way by casting to Utf8View but got a panic.
To Reproduce
let etld_values = LargeStringArray::from(vec!["com", "org", "net"]);
let etld_keys = UInt32Array::from(vec![0, 1, 0, 2]);
let etld: ArrayRef = Arc::new(DictionaryArray::new(etld_keys, Arc::new(etld_values)));
let result = cast(&etld, &DataType::Utf8View).unwrap();
assert_eq!(result.len(), 4);
dbg!(&result);Expected behavior
Should not panic and return a Utf8View (StringViewArray).
Or should panic higher up with a better error.
