You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: html_test.rs
    path of file: ./repos/rdms/src/web
    
    the code of the file until where you have to start completion: use std::{
    cel
    
fn test_html1() {
    let text = r"<!DOCTYPE html>";

    let mut lex = Lex::new(text.to_string());

    let parser = new_parser().unwrap();
    let node = parser.parse(&mut lex).unwrap().unwrap();
    assert_eq!(node.to_string(), text);
    let dom = Dom::from_node(node).unwrap();

    let ref_dom = Rc::new(Dom::Doc {
        doc_type: Some(Doctype { legacy: None }),
        root_elements: Vec::default(),
    });
    assert_eq!(dom, ref_dom);
}
