Importing local modules in an evcxr Jupyter Notebook

Hello all. New to the community, so I apologize if I'm messing something up. I'm new to Jupyter Notebook and evcxr as well. Let's say I have a struct in a src/models/ file:

use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize, Debug)]
pub struct Book {
    pub title: String,
    pub author: String,
    pub rating: f32,
    pub num_ratings: u64,
    pub year_published: u32,

How do I use that struct in a Jupyter Notebook? Obviously, if I were in another file, I would just do:

use crate::models::goodreads::Book;

But that doesn't work in a Jupyter Notebook.

I really appreciate the help! I've been hitting my head against this for a while.

Evcxr doesn't support code in external files. It only supports extern crates as dependencies and code inside the notebook itself.
