Function product_checked 

pub fn product_checked<T>(
    array: &PrimitiveArray<T>,
) -> Result<Option<<T as ArrowPrimitiveType>::Native>, ArrowError>
where
    T: ArrowNumericType,

Returns the product of values in the primitive array.

Returns Ok(None) if the array is empty or only contains null values.

This detects overflow and returns an Err for that. For an non-overflow-checking variant, use product instead.
