Hi! I’m from the RustRover team. RustRover is a full-blown IDE, not just a code analysis engine like rust-analyzer.

In addition to Rust code analysis, RustRover provides many features, including code linting, code formatting, dependency management (Cargo.toml editing), UI debugging, support for web technologies and databases, and AI support (including an agentic approach with Junie).

Comparing code analysis capabilities themselves is quite difficult, because Rust is a very complex language, especially when it comes to implementing IDE-level support. Features such as macros make this even more challenging. RustRover and rust-analyzer use different approaches to solving these problems, and we also share some components. Of course, neither approach is perfect. Depending on the specific project, the developer experience may vary.

rust analyzer fails 13 lines into my main.rs file because I use something rust analyzer just doesn't work with that well, also it's much faster
