teloxide

A full-featured framework that empowers you to easily build Telegram bots using the async/.await syntax in Rust. It handles all the difficult stuff so you can focus only on your business logic.

Getting started

1. Create a new bot using @Botfather to get a token in the format 123456789:blablabla.
2. Be sure that you are up to date:

$ rustup update stable

3. Execute cargo new my_bot, enter the directory and put these lines into your Cargo.toml:

[dependencies]
teloxide = "0.1.0"

Writing your first bot

Open main.rs file, because we're gonna write a ping-pong-bot!

use teloxide::prelude::*;

#[tokio::main]
async fn main() {
    // Configure a fancy logger. Let this bot print everything, but restrict
    // teloxide to only log errors.
    std::env::set_var("RUST_LOG", "ping_pong_bot=trace");
    std::env::set_var("RUST_LOG", "teloxide=error");
    pretty_env_logger::init();
    log::info!("Starting the ping-pong bot!");

    // Creates a dispatcher of updates with the specified bot. Don't forget to
    // replace `MyAwesomeToken` with yours.
    Dispatcher::<RequestError>::new(Bot::new("MyAwesomeToken"))
        // Registers a message handler. Inside a body of the closure, answer
        // `"pong"` to an incoming message.
        .message_handler(&|ctx: DispatcherHandlerCtx<Message>| async move {
            ctx.answer("pong").send().await?;
            Ok(())
        })
        .dispatch()
        .await;
}
