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: routes.rs
    path of file: ./repos/pavex/doc_examples/guide/request_data/wire_data/project/src/head
    
    the code of the file until where you have to start completion: use pavex::http::StatusCode;
use pavex::request::RequestHead;

pub fn handler(head: &RequestHead) -> St
    
pub fn handler(head: &RequestHead) -> StatusCode {
    println!("The HTTP method is {}", head.method);
    println!("The HTTP version is {:?}", head.version);
    println!("The request target is {}", head.target);
    println!("There are {} headers", head.headers.len());
    StatusCode::OK
}
