`docsrs_dep` is not a cfg attribute.

variadics_please version

v1.1.0

Relevant system information

This section is optional. Remove it if you know that the problem is not platform dependent.

Rust version you're using:

cargo 1.93.0 (083ac5135 2025-12-15)

Notes:

• Pay attention to the msrv (minimum supported rust version) of variadics_please.
• nightly should work, but sometimes there are regressions: please let us know!

Operating system, including version:

NixOS 26.05.20251218.c6245e8

What you did

When using the #[doc(fake_variadic)] feature, cargo emits the warning:

warning: unexpected `cfg` condition name: `docsrs_dep`
  --> golm/src/compiler_modules/syscall.rs:49:1
   |
49 | / all_tuples!(
50 | |     #[doc(fake_variadic)]
51 | |     impl_into_syscall,

56 | | );
   | |_^

   = help: expected names are: `docsrs`, `feature`, and `test` and 31 more
   = note: using a cfg inside a macro will use the cfgs from the destination crate and not the ones from the defining crate
   = help: try referring to `all_tuples` crate for guidance on how handle this unexpected cfg
   = help: the macro `all_tuples` may come from an old version of the `variadics_please` crate, try updating your dependency with `cargo update -p variadics_please`
   = note: see <https://doc.rust-lang.org/nightly/rustc/check-cfg/cargo-specifics.html> for more information about checking conditional configuration
   = note: `#[warn(unexpected_cfgs)]` on by default
   = note: this warning originates in the macro `all_tuples` (in Nightly builds, run with -Z macro-backtrace for more info)

What went wrong

I think this cfg attribute may have been removed? I can't find anything about it outside of Bevy.

Bevy configures this explicitly:
https://github.com/bevyengine/bevy/blob/74d3340729c781af7f978595367bfd332161137f/Cargo.toml#L5142-L514

For most people I think that level of paranoia is probably not needed and they can just use cfg(docsrs), which works by default.
