midnattsol opened a new issue, #6809:
URL: https://github.com/apache/arrow-rs/issues/6809
**Describe the bug**
When calling arrow::compute::take on an Array with non-nullable fields and
passing take indices that contain null values, the resulting Array contains
null values. This is an invalid state.
**To Reproduce**
```rust
use arrow::array::Array;
use arrow::array::{Int32Array, StringArray, StructArray};
use arrow::compute::take;
use arrow::datatypes::{DataType, Field};
use std::sync::Arc;
fn main() {
// Crear un StructArray con campos no anulables
let field1 = Int32Array::from(vec![Some(1), Some(2), Some(3)]);
let field2 = StringArray::from(vec![Some("a"), Some("b"), Some("c")]);
let struct_array = StructArray::from(vec![
(
Arc::new(Field::new("field1", DataType::Int32, false)),
Arc::new(field1) as Arc<dyn arrow::array::Array>,
),
(
Arc::new(Field::new("field2", DataType::Utf8, false)),
Arc::new(field2) as Arc<dyn arrow::array::Array>,
),
]);
// // Create an array of indices with null values
let indices = Int32Array::from(vec![Some(0), None, Some(2)]);
let field1_column = struct_array.column_by_name("field1").unwrap();
let field1_result = take(field1_column, &indices, None).unwrap();
let field1_result =
field1_result.as_any().downcast_ref::<Int32Array>().unwrap();
println!("Result field1: {:?}", field1_result);
let field2_column = struct_array.column_by_name("field2").unwrap();
let field2_result = take(field2_column, &indices, None).unwrap();
let field2_result = field2_result
.as_any()
.downcast_ref::<StringArray>()
.unwrap();
println!("Result field2: {:?}", field2_result);
}
```
**Output**
```sh
Result field1: PrimitiveArray<Int32>
[
1,
null,
3,
]
Result field2: StringArray
[
"a",
null,
"c",
]
```
**Expected behavior**
Using `take` with null indices on Array with no-nullable values should
return an error.
