Research direction
Start by locating String::from and the functions or traits that contain unwrap calls. Check the Rust 1.46 track_caller support described in the linked release post, then determine which entry points should expose caller information. Done means the relevant panic output includes a more useful call location, with tests or examples demonstrating the changed behavior.
