I saw this error in a minimal project that didn't have a rustfmt.toml. I was able to make the errors go away by creating a rustfmt.toml and adding an edition = "2018" to it. #12232

I can't close this issue, but @bjorn3's suggestion in #12233 (comment) is correct. You are on the 2015 edition, not the 2021 edition. The error message you pasted there says:

  = help: set `edition = "2021"` in `Cargo.toml`

Duplicate of #12233.
