Weird error -- the lazy_static 1.4.0 on crates.io definitely does not have a \0 byte on line 1 in Cargo.toml. Could you open up C:\Users\Douglas\.cargo\registry\src\github.com-1ecc6299db9ec823\lazy_static-1.4.0\Cargo.toml and confirm that it looks reasonable? Maybe something got corrupted in your cargo registry cache. Try deleting all of C:\Users\Douglas\.cargo\registry\src\github.com-1ecc6299db9ec823 and then trying cargo test again.

Weird, the toml file was binary. Thanks for the confirmation on deleting the registry, done. More strangeness: error: failed to download serde v1.0.99

Removed the registry and tried again, same error.

Something is wacky with your connection to crates.io that is resulting in receiving wrong data. I have seen something like this once before when an employer was MITM'ing https connections and mucking with the contents.

I am closing the issue because I don't think I will be able to debug this with you here, as it doesn't seem to be related to proc macros or this workshop. You could try asking in the Rust subreddit or discord for help debugging this.

Deleted my rust install, redid it, all good. Thanks for the responses and clues.
