Rather than turn off type coercion and inference, it sounds like you want a way to see the coerced/inferred types right in your editor. Rust Analyzer does this for you — there's a plugin for VSCode that will show inferred types as inline hints in your editor next to each expression, so you're never left guessing. Personally, I agree, Rust is nigh impossible to write without types in your editor; thankfully Rust Analyzer provides them.
