Heads up, @Lokathor, with the release of rust-lang/cargo#13913 (in nightly-2024-05-19). Cargo has now gain the ability to declare --check-cfg args directly inside the [lints] table with [lints.rust.unexpected_cfgs.check-cfg]1:

Cargo.toml:

[lints.rust]
unexpected_cfgs = { level = "warn", check-cfg = ['cfg(foo)'] }

Note that the diagnostic output of the lint has been updated to suggest the [lints] approach first. You can use it to guide you through the --check-cfg arguments that may need to be added.

Footnotes

  1. take effect on Rust 1.80 (current nightly), is ignored on Rust 1.79 (current beta), and produce an unused warning below ↩

Uh, if you wanna PR a fix for that I'll merge it. Both ways seem fine to me, I don't quite follow why it'd want it in Cargo.toml instead of in the source code
