use futures::StreamExt;
use telegram_bot::*;
#[tokio::main]
async fn main() -> Result<(), Error> {
let token = env::var("TELEGRAM_BOT_TOKEN").expect("TELEGRAM_BOT_TOKEN not set");
let api = Api::new(token);
// Fetch new updates via long poll method
let mut stream = api.stream();
while let Some(update) = stream.next().await {
// If the received update contains a new message...
let update = update?;
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.send(message.text_reply(format!(
"Hi, {}! You just wrote '{}'",
&message.from.first_name, data
)))
.await?;
}
}
}

}You can find a bigger examples in the examples.
Usage
This library is available via crates.io. In order to use it, just add this to your Cargo.toml:
telegram-bot = "0.7"
The library allows you to do E2E-testing of your bot easily: just specify TELEGRAM_API_URL environment variable to point to your fake Telegram test server.
A lot of diagnostic information can be collected with tracing framework, see example/tracing.rs).
