Problem on default sample code of weedle

[ccrashes]

Hi .

I've added a new rust project and used in test directory and the code looks like this (webgpu webidl):

use std::fs;
use std::io::Read;

fn read_file(path: &str) -> String {
    let mut file = fs::File::open(path).unwrap();
    let mut file_content = String::new();
    file.read_to_string(&mut file_content).unwrap();
    file_content
}

fn should_parse_webgpu_webidl() {
    let content = read_file("C:/weedle/tests/defs/webgpu.webidl");
    let parsed = weedle::parse(&content).unwrap();
    println!("{:?}", parsed);

    //// assert_eq!(parsed.len(), 201);
}

fn main() {
    should_parse_webgpu_webidl();    
}

I'm running this on windows but after cargo run command I'm getting this error :

What's the problem with this code? (I have installed Rust nightly on my system) .

Thanks .
