The OP is likely nothing more than wishful thinking, but I can see why people are intrigued by the prospect. An important thing to note is that it's entirely possible to perform a slow, gradual integration of Rust code into a C/C++ codebase (such as Mozilla is doing with Firefox), but only if your codebase is sufficiently modular with well-defined interfaces for Rust-based libs to slot into. If all you've got is a big ball of mud, then your first step is to work on the modularization of your codebase (which, IMO, has a good chance of increasing your code quality regardless of whether you eventually decide to introduce any Rust).
