+1 for that data point. The type system allows me to be much more explicit with regard to what I expect my code to do. And Rust-analyzer helps me spot those parts that don't fit together. But I typically turn it off, until I am actually done with defining all data types.

I also use assertions and unit tests, because the type system still has its limitations (or some things would be too awkward to express), but I can move forward a long way without actually compiling a project.
