Goto file for include!(...)

[Veetaha]

This is a feature request. I think it should not be hard to get a goto-file (maybe just via goto-definition lsp functionality) for include!(...) expressions and items.
This might work by invoking the goto-definition request on the path string literal expression in include!(<here>). This will greatly simplify navigating to code which resides in OUT_DIR.

As a second step it might be super-awesome if goto-definition requests for symbols defined in include!()ed files navigated the users exactly to the included files source instead of include!(...) expression

I just ran into this messing with capnproto include!(concat!(env!("OUT_DIR"), "/test_capnp.rs"));

Now when I tried Ctrl+Click the items defined in the include!()ed files the cursor only jumped to the end of the current file.
Expecting the exciting feature.

I've opened #6992 for go to definition on items defined in an included file; let's keep this about going to the file by clicking on the path itself.

I’ll give this a go if no-one else is already working on it.

It seems this feature doesn't work any more.

mod prometheus {
    include!(concat!(env!("OUT_DIR"), "/prometheus.rs"));
}
pub use prometheus::*;

Snippet above include prost-build generated output file, when invoke find definition on type defined in promtheus module, it will go to include!, not actual generated prometheus.rs

I don't think this feature worked with expressions other than the string literal like this include!("...")
