Formal definitions of preconditions and postconditions to verify that function behavior matches expectations.
Distinguishing note: Candidates describe UDFs (User-Defined Functions) for databases, not formal logic contracts for verification.

Kani is a formal verification tool and model checker for Rust. It functions as a bit-precise static analyzer that mathematically proves the correctness and memory safety of code by exhaustively analyzing program states to identify undefined behavior, panics, and logic errors. The tool identifies bugs by producing concrete counterexamples when program assertions or safety contracts are violated. It enables the definition of function contracts through preconditions and postconditions to verify that inputs and outputs match expected behavior. The system provides capabilities for Rust program an
Enables the definition of function contracts through preconditions and postconditions for verified abstractions.
