**Describe the bug** Track https://github.com/apache/arrow-rs/pull/1633#discussion_r863308866 We have the bug in `BinaryArray` and `StringArray` in the substring kernel. **To Reproduce** ```rust fn offset_fixed_size_binary() -> Result<()> { let values = *b"hellotherearrow"; let offsets: [i32; 4] = [0, 5, 10, 15]; // set the first and third element to be valid let bits_v = [0b101_u8]; let data = ArrayData::builder(DataType::Binary) .len(2) .add_buffer(Buffer::from_slice_ref(&offsets)) .add_buffer(Buffer::from_slice_ref(&values)) .offset(1) .null_bit_buffer(Buffer::from(bits_v)) .build() .unwrap(); // array is `[null, "arrow"]` let array = BinaryArray::from(data); // result is `[null, "rrow"]` let result = substring(&array, 1, None)?; let result = result .as_any() .downcast_ref::<BinaryArray>() .unwrap(); let expected = BinaryArray::from_opt_vec( vec![None, Some(b"rrow")], ); assert_eq!(result, &expected); Ok(()) } ``` **Expected behavior** 1. fix the bug 2. add tests **Additional context** Add any other context about the problem here. -- This is an automated message from the Apache Git Service.
