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: lib.rs
    path of file: ./repos/pavex/libs/pavex_cli/tests/ui_tests/borrow_checker/diamond/diamond_can_be_solved_if_we_can_clone
    
    the code of the file until where you have to start completion: use std::path::PathBuf;

use pavex::f;
use pavex::blueprint::{
    constructor::{CloningStrategy, Lifecycle},
    router::GET,
 
    
pub fn blueprint() -> Blueprint {
    let mut bp = Blueprint::new();
    bp.constructor(f!(crate::a), Lifecycle::RequestScoped)
        .cloning(CloningStrategy::CloneIfNecessary);
    bp.constructor(f!(crate::b), Lifecycle::RequestScoped)
        .cloning(CloningStrategy::CloneIfNecessary);
    bp.constructor(f!(crate::c), Lifecycle::RequestScoped);
    bp.constructor(f!(crate::d), Lifecycle::RequestScoped);
    bp.route(GET, "/home", f!(crate::handler));
    bp
}
