Here is a basic example to specify your Okapi key, and to retrieve the status from a given tracking number
// src/main.rs
#[tokio::main]
async fn main() {
let client = laposte::Client::new("your_api_key");
let res = client.get_tracking_info("the_tracking_number");
match res.await {
Ok(resp) => println!("Le colis n°{} est au statut {}", resp.shipment.id_ship, resp.shipment.event[0].label),
Err(_) => println!("Oh no")
};
}
