Argus: Interactively Debugging Rust trait Errors

Traits are a source of bewildering error messages in the Rust community and people have spent money and time trying to improve the resulting diagnostics. We took a different approach. We analyzed a community suite of difficult-to-debug trait errors and formed hypotheses about why they were difficult for engineers to debug. Then, we built an interactive debugger that developers can use in the IDE to debug trait errors. Find more details about our process, the tool, and our paper in our Cognitive Engineering
