Creusot provides formal verification for Rust by enabling contracts, invariants, and Pearlite specifications so that quality-critical code can be proven correct rather than relied on tests alone.
Annotate your Rust function with Creusot contracts and run cargo creusot prove to verify the function.

You can formally verify Rust code by annotating functions with Creusot contracts like #[requires], #[ensures], and Pearlite specifications, then running cargo creusot prove to discharge proof obligations.
To write loop invariants in Rust, use Creusot's #[invariant] and #[variant] annotations alongside Pearlite logic to express loop properties and termination measures for verifying iterative algorithms.
Yes, you can prove Rust function preconditions and postconditions by specifying them with Creusot's #[requires] and #[ensures] attributes, generating Why3/Coma models to mathematically verify correctness instead of testing.
Rust formal verification with Creusot fully supports Pearlite ghost and predicate logic, allowing you to define ghost variables and logical predicates to express complex proof requirements across Rust modules.
Debugging failed Creusot proofs involves inspecting the generated Why3/Coma models and reviewing your Pearlite specifications, loop invariants, and function contracts to identify logical gaps in the verification obligations.
Use formal verification for quality-critical Rust code where mathematical certainty is required, applying Creusot contracts and Pearlite specifications to prove correctness rather than relying on tests alone.
