use futures_util::StreamExt; use rutebot::client::Rutebot; use rutebot::requests::{SendMessage}; use rutebot::responses::Update; use std::error::Error;

[tokio::main]

async fn main() -> Result<(), Box> { let tokenenv = env::varos("TELEGRAMTOKEN") .expect("Please specify your bot's token in the TELEGRAMTOKEN environment variable."); let token = tokenenv.tostring_lossy();

let rutebot = Rutebot::new(token);
let mut updates_stream = Box::pin(rutebot.incoming_updates(None, None));
while let Some(update) = updates_stream.next().await.transpose()? {
    let create_reply_request = |update: Update| {
        let message = update.message?;
        let response_message = format!("Hello {}", message.from?.first_name);
        let reply =
            SendMessage::new_reply(message.chat.id, &response_message, message.message_id);
        Some(rutebot.prepare_api_request(reply))
    };

    if let Some(reply) = create_reply_request(update) {
        tokio::spawn(reply.send());
    }
}
Ok(())
