rustHow to calculate the sum of a Rust slice?

The sum of a Rust slice can be calculated using the iter() and sum() methods.

Example code

let v = vec![1, 2, 3, 4, 5];
let sum: i32 = v.iter().sum();

Output example

15

Code explanation

• let v = vec![1, 2, 3, 4, 5];: This line creates a vector v with elements 1, 2, 3, 4, and 5.
• let sum: i32 = v.iter().sum();: This line creates a variable sum of type i32 and assigns it the sum of the elements in v using the iter() and sum() methods.
