Rust debugging survey 2026

We're launching a Rust Debugging Survey . Various issues with debugging Rust code are often mentioned as one of the biggest challenges that annoy Rust developers. While it is definitely possible to debug Rust code today, there are situations where it does not work well enough, and the quality of debugging support also varies a lot across different debuggers and operating systems. In order for Rust to have truly stellar debugging support, it should ideally: Support (several versions!) of different debuggers (such as GDB, LLDB or CDB) across multiple operating systems. Implement debugger visualizers that are able to produce quality presentation of most Rust types. Provide first-class support for debugging async code. Allow evaluating Rust expressions in the debugger. Rust is not quite there yet, and it will take a lot of work to reach that level of debugger support. Furthermore, it is also challenging to ensure that debugging Rust code keeps working well, across newly released debugger v
