Traits exposed by proc_macro are not visibile for IDE completion.

[mehmooda]

If you have a proc macro attribute which generates a new trait. It doesn't seem to be visible to use in the current crate;

See https://github.com/mehmooda/glib_macro_test/blob/main/muse/src/main.rs

The proc macro attribute defines a MyWidgetExt trait with methods such as connect_my_signal and emit_my_signal. But they are not visible for auto completion and if you try to write use MyWidgetExt as Test; you get unresolved import. Even though cargo check is fine.

Proc macro attributes are not yet implemented. They are planned to be implemented during the current six week sprint though: #8486
