I think in the meantime there was a change that it is actually checked. For
example, I want to construct this schema:
```Rust
let flow_field = Field::new("flow", DataType::Float32, false);
let field_value_list = Field::new("Value",
DataType::FixedSizeList(Arc::from(flow_field), 3), false);
let schema = Schema::new(vec![field_value_list]);
```
So far, no problem.
But afterwards I use this builder to build the FixedSizeList.
```Rust
let mut flow_data = FixedSizeListBuilder::new(Float32Builder::new(), 3);
```
The problem is now, when I want to construct a `RecordBatch` from my schema
and the data output:
```Rust
let flow_column = Arc::new(flow_data.finish()) as Arc<dyn Array>;
RecordBatch::try_new(Arc::from(schema), vec![flow_column])?
```
I get the following error:
```
Invalid argument error: column types must match schema types, expected
FixedSizeList(Field { name: "flow", data_type: Float32, nullable: false,
dict_id: 0, dict_is_ordered: false, metadata: {} }, 3) but found
FixedSizeList(Field { name: "item", data_type: Float32, nullable: true,
dict_id: 0, dict_is_ordered: false, metadata: {} }, 3) at column index 0
```
Am I mistaken here or shouldn't that work?
