case_sensitive_file_extension_comparisons should suggest is_some_and

[nyurik]

Summary

The clippy::case_sensitive_file_extension_comparisons suggestion should not cause subsequent clippy lint.

Reproducer

I tried this code:

fn foo(v: &str)->bool {
    v.ends_with(".a")
}

fn main() {
    println!("test = {:?}", foo("test.a"));
}

I expected the suggestion to not cause any clippy warnings, but instead, it suggested to replace it with this:

2 ~     std::path::Path::new(v)
3 +         .extension()
4 +         .map_or(false, |ext| ext.eq_ignore_ascii_case("a"))

The suggested code produces this:

  = note: `#[warn(clippy::unnecessary_map_or)]` on by default
help: use is_some_and instead
  |
2 ~     std::path::Path::new(v)
3 +         .extension().is_some_and(|ext| ext.eq_ignore_ascii_case("a"))
  |
