Function arrow2::compute::arithmetics::basic::sub

pub fn sub<T>(
    lhs: &PrimitiveArray<T>, 
    rhs: &PrimitiveArray<T>
) -> PrimitiveArray<T> where
    T: NativeArithmetics + Sub<Output = T>, 

Subtracts two primitive arrays with the same type. Panics if the subtraction of one pair of values overflows.

Examples

use arrow2::compute::arithmetics::basic::sub;
use arrow2::array::Int32Array;

let a = Int32Array::from(&[None, Some(6), None, Some(6)]);
let b = Int32Array::from(&[Some(5), None, None, Some(6)]);
let result = sub(&a, &b);
let expected = Int32Array::from(&[None, None, None, Some(0)]);
assert_eq!(result, expected)
