[jira] [Created] (ARROW-11577) Concat kernel panics on slices of
string arrays
Ben Chambers created ARROW-11577:
------------------------------------
Summary: Concat kernel panics on slices of string arrays
Key: ARROW-11577
URL: https://issues.apache.org/jira/browse/ARROW-11577
Project: Apache Arrow
Issue Type: Bug
Components: Rust
Reporter: Ben Chambers
See the test case below:
{code:java}
#[test]
fn test_string_array_slices() -> Result<()> {
let input_1 = StringArray::from(vec!["hello", "A", "B", "C"]);
let input_2 = StringArray::from(vec!["world", "D", "E", "Z"]);
let arr = concat(&[
input_1.slice(1, 3).as_ref(),
input_2.slice(1, 2).as_ref(),
])?;
let expected_output = StringArray::from(vec!["A", "B", "C", "D", "E"]);
let actual_output = arr
.as_any()
.downcast_ref::<StringArray>()
.unwrap();
assert_eq!(actual_output, &expected_output);
Ok(())
}{code}
Fails with:
{noformat}
range end index 8 out of range for slice of length 7
