Looks just like VS Code and I think it’s still built on electron so take that as you will.
Most of the tools that make an IDE an IDE. Refactoring abilities are very limited and basic. Quickly navigating complex code bases becomes tricky. The code completion and type annotations are often missing or just plain wrong. When compared to something like essentially any IDE offered by JetBrains it just doesn’t stack up. Prior to RustRover being released I briefly tried to use VS Code for Rust using its LSP plugin, but it was just really bad in general, it utterly failed to analyze the code and provided almost no contextual help.
