Function polars::export::arrow::compute::arithmetics::basic::wrapping_mul_scalar

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

This is supported on crate feature compute_arithmetics only.

Wrapping multiplication of a scalar T to a PrimitiveArray of type T. It do nothing if the result overflows.

Examples

use arrow2::compute::arithmetics::basic::wrapping_mul_scalar;
use arrow2::array::Int8Array;

let a = Int8Array::from(&[None, Some(0x10)]);
let result = wrapping_mul_scalar(&a, &0x10);
let expected = Int8Array::from(&[None, Some(0)]);
assert_eq!(result, expected);
