**rust-analyzer version**: 0.3.1229-standalone (5c28ad193 2022-10-01) and 0.4.1236-standalone (61504c8d9 2022-10-08) **rustc version**: 1.64.0 (a55dd71d5 2022-09-19) **relevant settings**: N/A RA emits an error for the following code when `feature` is disabled: ```rust fn main() { #[cfg(feature = "feature")] my_fn(0, MyStruct(0)); #[cfg(not(feature = "feature"))] my_fn(MyStruct(0)); } struct MyStruct(u8); impl MyStruct { fn get_mut(&mut self) -> &mut u8 { let MyStruct(val) = self; val } } fn immutable(_: &u8) {} fn mutable(_: &mut u8) {} fn my_fn(#[cfg(feature = "feature")] _: u8, mut my_struct: MyStruct) { let val = my_struct.get_mut(); immutable(val); mutable(val); // expected &mut u8, found &u8 rust-analyzer(type-mismatch) } ``` However, it complies fine via `cargo run` Thank you!
