rust-analyzer version: rust-analyzer version: 0.3.1607-standalone (429a381 2023-07-30)

rustc version: rustc 1.71.1 (eb26296b5 2023-08-03)

relevant settings: default Windows rustup installation, VSCode 1.81.0

While playing around with toml crate (Rust newbie, just trying things) got few errors when my cursor after the dot in following code:

use std::{io::Read, fs::File};
use toml::Table;

fn main() {
    let mut buf = String::new();
    File::open("test.toml").unwrap().read_to_string(&mut buf).unwrap();
    let country = buf.parse::<Table>().unwrap();
    for line in country {
        println!("{}", line.1**.**);
    }
}

Cargo.toml

[package]
name = "toml_test"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
toml = "0.7.6"
