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

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

This is supported on crate feature compute_arithmetics only.

Checked addition of a scalar T to a primitive array of type T. If the result from the sum overflows then the validity index for that value is changed to None

Examples

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

let a = Int8Array::from(&[None, Some(100), None, Some(100)]);
let result = checked_add_scalar(&a, &100i8);
let expected = Int8Array::from(&[None, None, None, None]);
assert_eq!(result, expected);
