rutebot

Telegram bot api bindings for rust programming language.

Example

Simple echo bot. It listens all incoming messages and echos text messages, on other messages it replies with text "I can echo only text message".

use hyper::rt::{Future, Stream};

use rutebot::client::Rutebot;
use rutebot::requests::get_updates::{GetUpdatesRequest, AllowedUpdate};
use rutebot::requests::send_message::send_text_message::SendTextMessageRequest;
use rutebot::responses::{Message, Update};
use rutebot::requests::ChatId;

           allowed_updates: Some(&allowed_updates),

   let updates = rutebot.incoming_updates(&get_updates)
       .then(Ok)

                       Some(request)

                   .send()
                   .map(|_| ())
                   .map_err(|x| println!("Got error while sending message: {:?}", x));
               hyper::rt::spawn(send_future);
           }
           Ok(())
