If you submitted the test files in the past, you’ll not be able to receive newer versions. I don’t know if there’s anything the staff can do about it. If you need to, grab files from the github repo: https://github.com/exercism/rust/tree/main/exercises/practice
Looks like this as it’s complaining about some metadata.
C:\dev\Exercism\workspace\rust\gigasecond>exercism submit src/lib.rs Cargo.toml
Error:
The exercise you are submitting doesn't have the necessary metadata.
Please see https://github.com/exercism/website-copy/blob/main/pages/cli_v1_to_v2.md for instructions on how to fix it.
When I copied .exercism directory from the old solution to the new one, I was able to submit the solution.
