kani

Kani automatically checks for many kinds of undefined behavior, which is especially useful for verifying unsafe Rust code blocks where compiler checks are relaxed, as highlighted in the README.

It verifies absence of panics (e.g., from unwrap on None) and arithmetic overflows, ensuring robust error handling and numerical safety without runtime overhead.

Supports custom assertions and function contracts through proof harnesses with kani::any(), allowing developers to prove specific correctness properties beyond standard checks.

Provides a GitHub Action for seamless integration into continuous integration workflows, enabling automated verification in development pipelines as documented in the README.
