Debugging Trait Errors as Logic Programs

Explore a proposed solution for debugging trait errors in Rust programming during this 30-minute conference talk presented at ACM SIGPLAN. Delve into the challenges posed by the increasing number of traits in Rust libraries and the resulting complexity in compiler diagnostics. Learn about the concept of a trait debugger, designed to extract proof trees from the trait solver and interactively visualize them. Discover how this tool aims to empower developers with the necessary information to diagnose trait errors across various domains and scales, addressing the limitations of current ad-hoc solutions created by crate maintainers.
