Vscode-rust: Cannot goto definition for std library types/functions

[doxxx]

Given the following:

use std::fs::File;
use std::path::Path;

fn main() {
    let ref mut fout = File::create(&Path::new("out.png")).unwrap();
}

Ctrl-click on File or Path in the main function simply does nothing, while ctrl-click on create or new produces a popup error in VS Code:

Unable to open 'fs.rs': File not found (c:\Program Files (x86)\Microsoft VS Code\src\libstd\fs.rs).

Or:

Unable to open 'path.rs': File not found (c:\Program Files (x86)\Microsoft VS Code\src\libstd\path.rs).

I have no user settings defined in VS Code for rust.

rustc 1.21.0-nightly (ba1d065ff 2017-08-06)

I have this same issue too with Windows 10 & rustc 1.21.0-nightly (f14249953 2017-08-09), with these errors (using the example with File and Path):

Of course, it works fine with the racer fallback setting turned on

Happens on linux too.

macOS 10.13 (beta) as well

Same here with Debian 9 and rustc 1.20.0 (stable). RUST_SRC_PATH is already set.

The popup error shows (for example) Unable to open file “mod.rs”: File not found (/checkout/src/libcore/fmt/mod.rs). I am curious about the checkout in the path. What is that?

However, it works for libraries installed by cargo. The issue only happens for std libraries.

On my windows machine it's looking for error.rs in:

c:\Program Files\Microsoft VS Code\src\libstd instead of
c:\Users\jkolb\.rustup\toolchains\nightly-x86_64-pc-windows-msvc\lib\rustlib\src\rust\src\libstd
