+[rustfmt] is a Rust code formatter that is widely used across the Rust ecosystem thanks to its direct integration within Cargo. Usually, you just run `cargo fmt` and you can immediately enjoy a properly formatted Rust project. However, there are edge cases in which `rustfmt` can fail to format your code. That is not such an issue on its own, but it becomes more problematic when it fails *silently*, without giving the user any context about what went wrong. This is what sometimes happens in `rustfmt`, due to technical debt that made it difficult to add proper error reporting in all situations.
+
+The goal of SeoYoung's project was to perform a large internal refactoring of `rustfmt` that would allow tracking context about what went wrong during reformatting. In turn, this would enable turning silent failures into proper error messages that could help users examine and debug what went wrong. It could even allow `rustfmt` to retry formatting in more situations.
