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: parse_error.rs
    path of file: ./repos/salvo/crates/core/src/http/errors
    
    the code of the file until where you have to start completion: use std::fmt::Debug;
use std::io::Error as IoError;
use std::str::Utf8Error;

    
    async fn test_write_error() {
        let mut res = Response::default();
        let mut req = Request::default();
        let mut depot = Depot::new();
        let err = ParseError::EmptyBody;
        err.write(&mut req, &mut depot, &mut res).await;
    }
