> No, it won't. A compiler and an IDE code analyzer have completely different non-intersecting goals.
That's the conventional wisdom. The rust team's theory was that they could make it work. They did.
> As an example, consider error recovery. Where a compiler can just fail with an error, in an IDE you need to continue to provide full correct syntax highlighting, display all other potential errors and warnings, continue providing code analysis (including suggestions on how to fix the error) etc.
Possibly the Rust compiler's unusual prioritization of friendly error messages with helpful suggestions meant this wasn't as big a difference as you thought?

That's how it works for many languages: the language server implementation is a thin wrapper around an existing tool. That's not the case for rust. I've watched the work the Rust language server team did on their language server implementation and the compiler. It was impressive.
