Verus is a tool for verifying the correctness of code written in Rust. Developers write specifications of what their code should do, and Verus statically checks that the executable Rust code will always satisfy the specifications for all possible executions of the code. Rather than adding run-time checks, Verus instead relies on powerful solvers to prove the code is correct. Verus currently supports a subset of Rust (which we are working to expand), and in some cases, it allows developers to go...
