Async Rust framework for the Telegram Bot API.

rustigram re-exports all sub-crates through a single dependency and a convenient [prelude] module covering the most common types.

Getting started

Add to Cargo.toml:

[dependencies]
rustigram = "0.9"
tokio     = { version = "1", features = ["full"] }

use rustigram::prelude::*;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let bot = Bot::new(std::env::var("BOT_TOKEN")?)?;

    bot.dispatcher()
        .on(filters::command("start"), handler_fn(start))
        .on(filters::message(),        handler_fn(echo))
        .build()
        .polling()
        .await?;

    Ok(())
}

async fn start(ctx: Context) -> BotResult<()> {
    if let Some(r) = ctx.reply("Hello!") { r.await?; }
    Ok(())
}

async fn echo(ctx: Context) -> BotResult<()> {
    if let (Some(text), Some(chat_id)) = (ctx.text(), ctx.chat_id()) {
        ctx.bot.send_message(chat_id, text).await?;
    }
    Ok(())
}
