Ha, apologies, fzy was a typo for `fd`. Too many installs on the brain.

Installs of rust itself aren't succeeding yet for me via Homebrew, with what look like likely simple errors but not ones I investigated yet (though yeah I saw the Rust tracking ticket you linked).

But e.g. retrying `brew install rust` this morning produces 404 errors trying to download https://static.rust-lang.org/dist/2020-08-27/rust-std-1.46.0...

It looks like https://github.com/Homebrew/homebrew-core/pull/65286 may fix things. Haven't spent a ton of time investigating though. Obviously if you have recommendations would love them.

Will have a look at your README, thanks for writing it.
