telebot 0.0.4

A wrapper around the telegram bot api, powered by futures

Telebot - Telegram Bot Library in Rust

This library allows you to write a Telegram Bot in Rust. It's an almost complete wrapper for the Telegram Bot API and uses tokio-curl to send a request to the Telegram server. Each Telegram function call returns a future.


Add this to your Cargo.toml toml [dependencies] telebot = "0.0.3"

Find a Telegram function in the source code

All available functions are listed in src/ For example consider sendLocation:

/// Use this method to send point on the map. On success, the sent Message is returned.
#[derive(TelegramFunction, Serialize)]
#[function = "sendLocation"]
#[answer = "Message"]
#[bot_function = "location"]
pub struct SendLocation {
    chat_id: u32,
    latitude: f32,
    longitude: f32,
    disable_notification: Option<bool>,
    reply_to_message_id: Option<u32>,
    reply_markup: Option<NotImplemented>

The field "answer" defines the name of the function in the local API. Each optional field in the struct can be changed by calling the function with the name of the field. So for example to send a location silently: bot.location(432432, 48.8566, 2.3522).disable_notification(true).send()
