List of Rust kata that needs to be updated. Note that the reason to update is not limited to the runner change. Any content issue that should be addressed can be listed here.

Rust 1.56 (edition = "2021") will be added soon. This section lists the incompatible kata that was found during testing. Most of these can be updated to prepare for the update.

Basically, assert!(x, format!("{} {} {}", a, b, c)); should be assert!(x, "{} {} {}", a, b, c);.
