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);
