Problem you are trying to solve
I was trying to build https://github.com/rust-lang/www.rust-lang.org and encountering some very confusing behavior - it was complaining about edition 2021 stuff, even though I am using the latest nightly as my default toolchain.
Eventually I thought to check
rustup toolchain list, and saw:I had never heard of overrides before! The first place I checked was
rustup toolchain help, which didn't mention them. I search "rustup override", and found https://rust-lang.github.io/rustup/overrides.html, which answered my question; but I got confused again because, skimming, I just looked at the "directory override" and concluded I had none.Solution you'd like
