DELETE – Deleting data

When we don't need data anymore, we can delete it. This is the purpose of the DELETE method. Use it in the branch as follows:

(&Method::DELETE, Some(id)) => {    if users.contains(id) {        users.remove(id);        response_with_code(StatusCode::OK)    } else {        response_with_code(StatusCode::NOT_FOUND)    }},

This code checks whether the Slab contains the data and removes it with the remove method. We don't use the remove method right away because this expects the data to exist in the storage beforehand, and therefore panics if the data is absent.

Often, web services don't actually remove data and instead just mark it as deleted. This is a reasonable thing to do because it allows you to explore the data later and improve the efficiency ...
