> I questioned my sanity every time I circled back around to the Clippy issue above. Surely, I was wrong. There must be a configuration I missed. I couldn’t believe it. I still can’t. Surely there must be a way to configure lints globally. I quadruple-checked when I wrote this to make sure I wasn’t delusional.

You create a .cargo/config.toml in the workspace root so it covers all your crates.

inside the file:

  [build]
  rustflags = ["-Wclippy::lint_name_to_warn", "-Dclippy::lint_name_to_deny"]

The only limitation is that rustflags are not additive, so if you have other sources of rustflags like the RUSTFLAGS environment variable it will overwrite this setting.
