No auto-completion for macro results

[Noah11012]

When using a macro such as vec! and then trying to call a method on the vector, no auto-completion comes up.

Code:

fn main() {
    let v = vec![1, 2, 3];
    v. // No auto-completion appears
}

This is a problem with Racer, which is embedded in the RLS. I don't think there is anything actionable here - Racer can't be made to understand macros, but eventually we will use the compiler instead.

eventually we will use the compiler instead.

Thanks for this. Being new to rust, I like learning a language through exploration, and auto-completion in my editor makes it possible for me to gradually go down the rabbit hole of the standard library and what I can do with what type. Hitting this while working on some toy code, I was also confused by this.

I am curious to hear if there's some kind of up-to-date roadmap on what has already been done on the compiler side to support this (or basically all RLS features), and what still has to be done?

Also a quick follow-up. Is this the same reason why the following doesn't work?

Any way to find out what works, and what doesn't work (aside from trying, but then I'm wondering if I should file a bug report, or not)? I looked over in the Racer repository, but couldn't find anything in the documentation about this.

@JeanMertz your latter sample isn't a macro, so you should probably file an issue.
