The concept of "verifiable code" is effectively dead - even C#'s own syntax is sometimes desugared into what one could consider "unsafe" code in terms of feature use. Unsafe code is safe when used correctly, it does not imply the reliance on undefined or implementation-defined behavior :) For all intents and purposes, the non-unsafe subset of Rust is a safe language, and the distinction pretty much does not exist at the IL level.
