pub fn apply_int_u64(
lhs: &[u64],
rhs: &[u64],
op: ArithmeticOperator,
mask: Option<&Bitmask>,
) -> Result<IntegerArray<u64>, KernelError>Expand description
Performs element-wise integer ArithmeticOperator over two &[u64], SIMD-accelerated using W64 lanes if available, otherwise falls back to scalar. Returns IntegerArray<u64> with appropriate null-mask handling.
