pub fn apply_int_i64(
lhs: &[i64],
rhs: &[i64],
op: ArithmeticOperator,
mask: Option<&Bitmask>,
) -> Result<IntegerArray<i64>, KernelError>Expand description
Performs element-wise integer ArithmeticOperator over two &[i64], SIMD-accelerated using W64 lanes if available, otherwise falls back to scalar. Returns IntegerArray<i64> with appropriate null-mask handling.
