Crate rutebot

Crate with bindings to telegram bot api. For usage details see example below and tests in basic_req_res_tests.rs. You can find all implemented methods in requests module.

Example

A simple greetings bot. Replies to all messages with text "Hello %USERNAME%"

use std::env;

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<dyn Error>> {
   let token_env = env::var_os("TELEGRAM_TOKEN")
       .expect("Please specify your bot's token in the TELEGRAM_TOKEN environment variable.");
   let token = token_env.to_string_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(())
}
