Implementing GET users

Now, let's implement get_users(). Here is a quick reminder of what the function looked like in the previous chapter:

#[get("/users?<_pagination>", format = "text/html")]

pub async fn get_users(

    mut _db: Connection<DBConnection>,

    _pagination: Option<Pagination>,

) -> HtmlResponse {

    todo!("will implement later")

}

As before, we should prepare the routines we're going to use:

1. In src/models/user.rs, create a method called find_all, as in the following:

   use super::pagination::{Pagination};
   use crate::fairings::db::DBConnection;
   use rocket_db_pools::Connection;
   use rocket_db_pools::sqlx::{Acquire, FromRow, PgConnection};
   ...
   impl User {
   ...
       pub async fn find_all(
           db: &mut Connection<DBConnection>,
       &...
