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: object.rs
    path of file: ./repos/simd-json/src/value/tape
    
    the code of the file until where you have to start completion: use std::{borrow::Borrow, hash::Hash};

use super::Value;
use crate::Node;

/// Wrapper around the tape that allows interacting with it via a `Object`-like API.

pub struct Object<'tape, 'input>(pub(super) &'tape [Node<'input>]);

pub struct ObjectIter<'tape, 'input>(&'tape [Node<'input>]);
pub struct ObjectKeys<'tape, 'input>(&'tape [Node<'inpu
    
    fn values_container() -> crate::Result<()> {
        let mut input =
            br#"{"snot": 1, "badger":[2, 2.5], "cake":{"frosting": 3}, "cookie":4}"#.to_vec();
        let t = to_tape(input.as_mut_slice())?;
        let v = t.as_value();
        let v = v
            .as_object()
            .expect("is an object")
            .values()
            .map(|v| v.as_u64())
            .collect::<Vec<_>>();
        assert_eq!(v, vec![Some(1), None, None, Some(4)]);

        Ok(())
    }
