Rust's `std` offers the [`Wrapping`](std::num::Wrapping) type for "intentionally wrapping" arithmetic, but curiously does not provide analagous implementations for intentionally saturating, checked, overflowing or panicking arithmetic. This crate addresses these missing wrappers as well as re-exports `std`'s [`Wrapping`](std::num::Wrapping) type for completeness and consistency.
