Function product 

Source 
pub fn product<T>(collection: &[T]) -> T
where
    T: Mul<Output = T> + Copy + From<u8>,
Expand description

Calculate the product of all elements in a collection. If the collection is empty, returns 1 (multiplicative identity). Works with any numeric type that implements std::ops::Mul and can be copied.

§Arguments

  • collection - A slice of numbers.

§Returns

  • T - The product of all numbers in the collection.

§Examples

use lowdash::product;

// Integer product
let numbers = vec![1, 2, 3, 4, 5];
assert_eq!(product(&numbers), 120);
use lowdash::product;

// Float product
let numbers = vec![1.5, 2.0, 3.0];
assert_eq!(product(&numbers), 9.0);
use lowdash::product;

// Empty collection returns 1
let empty: Vec<i32> = vec![];
assert_eq!(product(&empty), 1);
