Usage of `tokio::select!` triggers `redundant_pub_crate` (nursery)

[barafael]

Summary

On nursery lint level, any usage of tokio::select! wrongly triggers the redundant_pub_crate lint.

Lint Name

redundant_pub_crate

Reproducer

I tried this code:

use std::future::Future;
use tokio::select;

pub async fn selects(number: impl Future<Output = i32>, boolean: impl Future<Output = bool>) {
    select! {
        n = number => {
            println!("A number: {n}");
        },
        b = boolean => {
            println!("A boolean: {b}");
        }
    }
}

I saw this happen:

  --> src\lib.rs:5:5
   |
5  | /     select! {
6  | |         n = number => {
7  | |             println!("A number: {n}");
8  | |         },
...  |
11 | |         }
12 | |     }

   = note: `-W clippy::redundant-pub-crate` implied by `-W clippy::nursery`
   = help: to override `-W clippy::nursery` add `#[allow(clippy::redundant_pub_crate)]`
   = note: this warning originates in the macro `$crate::select_priv_declare_output_enum` which comes from the expansion of the macro `select` (in Nightly builds, run with -Z macro-backtrace for more info)

I expected to see this happen: no lint triggered on select!.
