Implementations

impl TelegramBot

pub fn new(bot_token: String, allowed_user_ids: Vec<i64>) -> Self

Create a new TelegramBot with the given token and allowed user IDs.

pub fn from_config(config: &ChannelConfig) -> Option<Self>

Build a TelegramBot from a ChannelConfig.

Returns None if no bot token is available — checks the config’s bot_token field first, then falls back to the BATTY_TELEGRAM_BOT_TOKEN environment variable.

pub fn is_authorized(&self, user_id: i64) -> bool

Check whether a Telegram user ID is in the allowed list.

An empty allowed_user_ids list denies everyone.

pub fn send_message(&self, chat_id: &str, text: &str) -> Result<()>

Send a text message to a Telegram chat.

Messages longer than 4096 characters are split into multiple messages. POST https://api.telegram.org/bot{token}/sendMessage

pub fn poll_updates(&mut self) -> Result<Vec<InboundMessage>>

Poll the Telegram Bot API for new updates and return authorized inbound messages.

GET https://api.telegram.org/bot{token}/getUpdates?offset={}&timeout=0

Unauthorized messages are silently dropped (logged at debug level).
