unwrap-overflow-ops

Arithmetic operations that always panic overflow, providing a polyfill for the [unwrap_overflow_ops feature].

To avoid conflicts with the standard library, methods are prefixed with unwrap_ instead of strict_. For example [i32::strict_add] becomes [UnwrapOverflowOps::unwrap_add].

Methods are available through the [UnwrapOverflowOps] extension trait. Some methods are only supported for signed/unsigned integers, and require [UnwrapOverflowOpsSigned] or [UnwrapOverflowOpsUnsigned].

Import the entire crate to use all three traits: use strict_overflow_ops::*;

Example

use unwrap_overflow_ops::*;

assert_eq!(0i32.unwrap_add(5), 5);
assert_eq!(7u32.unwrap_add_signed(-3), 4);
assert_eq!(-7i32.unwrap_neg(), 7);
