Support Goto Definition into `include!`

[cynecx]

settings.json (vscode):

{
    "rust-analyzer.cargoFeatures.loadOutDirsFromCheck": true,
}

rust-analyzer: 1c2d4135db867efe335a0654d86429bea7bb9caf (current master)

How to reproduce:

1. Add lapin = { version = "0.34" } to your deps.
2. Use this code snippet:

use lapin::{
    message::Delivery,
    options::{BasicAckOptions, BasicConsumeOptions, BasicRejectOptions},
    types::FieldTable,
    Connection, ConnectionProperties,
};

BasicAckOptions, BasicConsumeOptions and BasicRejectOptions come from proc-macro. "Go to definition" doesn't work on them. It works but redirects you a wrong source-site.

Goto definition do not work in include! macro yet. Do completion show them correctly ?

[cynecx]

Oh, I see. Yes, completions do work. Is there an already opened issue for that? (So I might close this one.)

[edwin0cheng]

@cynecx This is the first issue for that :)

[cynecx]

@edwin0cheng I am currently on master. And it seems that it's broken (In terms of it doesn't even find/resolve items). I am not quite sure when it broke though. I haven't realized since today when I came across this again.

Nevermind, it seems that the option changed from rust-analyzer.cargoFeatures.loadOutDirsFromCheck to rust-analyzer.cargo.loadOutDirsFromCheck.

Maybe we update the title? I was about to open an issue for include! macros not being followed for goto definition.

What is missing for this to be supported?
