rust library to interact with the openmensa api

---

Basic usage 🔧

This library provides a way to build request to the openmensa api and deserialize into rust structures. Provided are requests for Canteen, Meal and Day.

Requesting a list of all canteens

use openmensa_rs::request::CanteenRequest;

#[tokio::main]
async fn main() {
    println!("List of all canteens: ");
    let list = CanteenRequest::new().build().await;
    println!("{:?}", list);
}

Requesting the meals for a single canteen

use openmensa_rs::{req_canteens, request::MealRequest};

#[tokio::main]
async fn main() {
    let list = req_canteens().await.unwrap();
    // Print out the meals offered in the first canteen
    println!("Meals in the {} canteen on the {}", list[0].name(), chrono::Utc::today());
    let meals = MealRequest::new(list[0].id(), chrono::Utc::today())
        .build()
        .await
        .unwrap();
    println!("{:?}", meals);
}

Shorthands for generic requests

If you want to get all information and specify no further constraints for your requests, you can use the provided shorthands req_canteens, req_days and req_meals.

use openmensa_rs::req_canteens;

#[tokio::main]
async fn main() {
    let list = req_canteens().await.unwrap();
    println!("First canteens has id {} and is called {}", list[0].id(), list[0].name());
}
