How to reproduce the problem from neovim/Vim startup (Required!)

1. Install Rust
   * curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
2. Install rust-analyzer
   * Place rust-analyzer to rust-analyzer where the path passes.
3. cargo new foo
4. cd foo
5. nvim src/main.rs
6. Type the following:

struct Point {
    x: f64,
    y: f64,
}
fn main() {
    let p = Point::from(1.0);
    p.x;
}

7. Completion is displayed after entering the semicolon.
