Prusti is a static verifier for Rust that formally proves absence of panics, integer overflows, and other bugs, and checks user-specified contracts such as preconditions, postconditions, and loop invariants. It is built on the Viper verification infrastructure and leverages Rust's ownership type system to simplify specifications.

Use cases

• formally verify rust code correctness
• prove absence of panics and integer overflows in rust
• check preconditions and postconditions on rust functions
• verify loop invariants in rust programs
• statically analyze rust code for bugs
• specify and check functional contracts in rust

When to choose

• you need formal correctness guarantees for safety-critical Rust code
• you want to prove absence of panics and overflows beyond what the type system provides
• you are doing research or teaching in program verification with Rust

When to avoid

• you only need conventional testing or linting rather than formal proofs
• your codebase relies heavily on unsafe Rust, which is largely unsupported
• you need a mature production tool rather than a prototype verifier
