Sum_Range

This crate provides a trait for efficiently calculating the sum of numbers within a range, including support for odd and even number sums.

Supported Range Types

• Range
• RangeInclusive
• RangeTo
• RangeToInclusive

Trait Methods

• sum_range: Calculates the sum of all numbers in the range.
• sum_odd_range: Calculates the sum of all odd numbers in the range.
• sum_even_range: Calculates the sum of all even numbers in the range.

Note

• For RangeTo and RangeToInclusive, signed integer types are not supported.

Usage

use sum_range::SumRange;

assert_eq!((1..11).sum_range(), 55u8);
assert_eq!((0..=12).sum_range(), 78u8);
assert_eq!((-10..12).sum_odd_range(), 11i16);
assert_eq!((-5..=5).sum_even_range(), 0i32);

lib.rs:

This crate provides a trait for calculating the sum of numbers in a range.

The trait is implemented for the following types:

• Range
• RangeInclusive
• RangeTo
• RangeToInclusive

The trait provides three methods:

• sum_range
• sum_odd_range
• sum_even_range

The methods calculate the sum of the numbers in the range, the sum of the odd numbers in the range, and the sum of the even numbers in the range, respectively.

Examples

use sum_range::SumRange;

assert_eq!((1..11).sum_range(), 55u8);
assert_eq!((0..=12).sum_range(), 78u8);
assert_eq!((-10..12).sum_odd_range(), 11i16);
assert_eq!((-5..=5).sum_even_range(), 0i32);
