HTTP client and typed method builders for the Telegram Bot API.

The central type is [BotClient], which is cheap to clone (all state is behind an Arc) and safe to share across tasks. Every Bot API method is exposed as a builder that returns a future:

let message = client
    .send_message(chat_id, "Hello!")
    .parse_mode(ParseMode::HTML)
    .disable_notification(true)
    .await?;

Error handling

All methods return [Result<T>]. The [Error] type covers API-level failures (bad token, flood control, missing permissions), transport errors, and serialisation failures. Rate-limit errors (HTTP 429) are automatically retried by the polling engine in rustigram-bot; individual API calls surface them as [Error::RateLimit].

Feature flags

Re-exports

The [methods] module re-exports every builder type. You generally do not need to import them directly — call the corresponding method on [BotClient] and the builder is returned.
