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: lazy_static.rs
    path of file: ./repos/once_cell/examples
    
    the code of the file until where you have to start completion: extern crate once_cell;

use once_cell::sync::{Lazy, OnceCell};
use std::collections::HashMap;

static HASHMAP: Lazy<HashMap<u32, &'static str>> = Lazy::new(|| {
    let mut m = HashMap::new();
    m.insert(0, "foo");
    m.insert(1, "bar");
    m.insert(2, "baz");
    m
});


    
fn main() {
    // First access to `HASHMAP` initializes it
    println!("The entry for `0` is \"{}\".", HASHMAP.get(&0).unwrap());

    // Any further access to `HASHMAP` just returns the computed value
    println!("The entry for `1` is \"{}\".", HASHMAP.get(&1).unwrap());

    // The same works for function-style:
    assert_eq!(hashmap().get(&0), Some(&"foo"));
    assert_eq!(hashmap().get(&1), Some(&"bar"));
}
