Another, very similar verified superset of Rust is Creusot. I’m not sure what the benefits/downsides of each are besides syntax tbh.

This is also similar to Kani which also verifies Rust code. However, Kani is a model checker like TLC (the model checker for TLA+), while Verus and Creusot are SMT solvers like Dafny.

Interestingly, Verus (unlike both Kani and Creusot) has its language server, which is a fork of rust-analyzer (verus-analyzer).
