"consider calling .len() instead"
(you can skip the ":" here I think, looks like it is already inserted in the warning message automatically? (see tests output)

I have addressed this commit about this comment, but I think we need to add a test that addresses this fix. How do I add a test about this case? |

Although struct Foo<'a> {
str: &'a str,
}
impl Foo<'_> {
fn bytes(&self) -> std::str::Bytes<'_> {
self.str.bytes()
}
}
fn main() {
let f = Foo { str: "foo" };
let _ = f.bytes().count();
} |
formats code with fixes single match clippy error to replace with if let swaps ident.name.as_str to ident.name == sym for count fn
adding test patterns cargo dev bless fix comment add ; delete : fix suggestion code and update stderr in tests. use match_def_path when checking method name

Remove `dead_code` paths The following paths are `dead_code` and can be removed: ### `clippy_utils::paths::VEC_RESIZE` * Introduced when `vec_resize_to_zero` lint added in PR #5637 * No longer used after commit 8acc4d2 ### `clippy_utils::paths::SLICE_GET` * Introduced when `get_first` lint added in PR #8882 * No longer used after commit a8d80d5 ### `clippy_utils::paths::STR_BYTES` * Introduced when `bytes_count_to_len` lint added in PR #8711 * No longer used after commit ba6a459 When the lints were moved into the `Methods` lint pass, they switched from using paths to diagnostic items. However, the paths were never removed. This occurred in PR #8957. This relates to issue #5393 changelog: none
