let token = env::var("TELEGRAM_BOT_TOKEN").unwrap();
let api = Api::new_default(token).unwrap();
// Convert stream to the stream with errors in result
let stream = api.stream().then(|mb_update| {
let res: Result<Result<Update, Error>, ()> = Ok(mb_update);
res
});
// Print update or error for each update.
stream.for_each(move |update| {
match update {
Ok(update) => {
// If the received update contains a new message...
if let UpdateKind::Message(message) = update.kind {
if let MessageKind::Text { ref data, .. } = message.kind {
// Print received text message to stdout.
println!("<{}>: {}", &message.from.first_name, data);
// Answer message with "Hi".
api.spawn(message.text_reply(format!(
"Hi, {}! You just wrote '{}'",
