Problem
The
fmt::Displayimplementation forConstraintTraceusedmetadata.module_path().unwrap(), which could panic if the module path is not available for certain spans (e.g., from macros or external sources).Solution
Replace
unwrap()withunwrap_or(metadata.target())to provide a safe fallback using the span's target as an alternative identifier.Changes
