Merge #3880
3880: Add support for attributes for struct fields r=matklad a=bnjjj Hello I try to solve this example: ```rust struct MyStruct { my_val: usize, #[cfg(feature = "foo")] bar: bool, } impl MyStruct { #[cfg(feature = "foo")] pub(crate) fn new(my_val: usize, bar: bool) -> Self { Self { my_val, bar } } #[cfg(not(feature = "foo"))] pub(crate) fn new(my_val: usize, _bar: bool) -> Self { Self { my_val } } } ``` Here is a draft PR to try to solve this issue. In fact for now when i have this kind of example, rust-analyzer tells me that my second Self {} miss the bar field. Which is a bug. I have some difficulties to add this features. Here in my draft I share my work about adding attributes support on struct field data. But I'm stuck when I have to fetch attributes from parent expressions. I don't really know how to do that. For the first iteration I just want to solve my issue without solving on all different expressions. And then after I will try to implement that on different kind of expression. I think I have to fetch my FunctionId and then I will be able to find attributes with myFunction.attrs() But I don't know if it's the right way. @matklad (or anyone else) if you can help me it would be great :D Co-authored-by: Benjamin Coenen <5719034+bnjjj@users.noreply.github.com>
