Hi Roland, For primitive types, there are value_slice methods which would allow you to get the array's contents as a vector, but you have to handle the null values as the vectors wouldn't return an Option<T>. We haven't seen demand yet in converting arrays to JSON, but the integration crate ( https://github.com/apache/arrow/blob/master/rust/integration-testing/src/bin/arrow-json-integration-test.rs#L420) would contain some logic to convert to JSON already.
