Crate rust_tg_bot_ext 

Application framework for Telegram bots.

rust-tg-bot-ext provides the high-level handler/filter/persistence layer on top of rust_tg_bot_raw. It is modeled after Python’s python-telegram-bot extension package and offers:

• Handlers: CommandHandler, MessageHandler, CallbackQueryHandler, etc.
• Filters: composable with &, |, ^, ! operators via F.
• Persistence (feature persistence): in-memory (DictPersistence) and JSON-file (JsonFilePersistence).
• Application: the main dispatch loop (Application).

Quick start

use rust_tg_bot_ext::prelude::*;

async fn start(update: Update, context: Context) -> HandlerResult {
    context.reply_text(&update, "Hello!").await?;
    Ok(())
}

let app = ApplicationBuilder::new("BOT_TOKEN").build().await;
app.add_handler(CommandHandler::new("start", start), 0).await;
app.run_polling().await?;
