}

Backend that executes reaction-moderation API calls.

Implementors are expected to call the Telegram Bot API. The trait is object-safe (all methods return pinned boxed futures) so ModerationExecutor can hold it as Arc<dyn ReactionModerationBackend>.

Contract

• delete_reaction and delete_all_reactions must call the Telegram API and surface both ok: false responses as ModerationError::Api and transport failures as ModerationError::Http.
• The bot must be an administrator with appropriate rights in the target chat before calling these methods; implementations SHOULD perform a pre-flight get_chat_member check and return ModerationError::Api when the bot is not an administrator, rather than forwarding a Forbidden error from the API.

Required Methods

fn delete_reaction<'a>( &'a self, chat_id: i64, message_id: i64, user_id: i64, reaction: &'a str, ) -> Pin<Box<dyn Future<Output = Result<(), ModerationError>> + Send + 'a>>

Remove a single reaction left by user_id on a message.

Errors

Returns ModerationError on API or transport failure.

fn delete_all_reactions<'a>( &'a self, chat_id: i64, message_id: i64, user_id: i64, ) -> Pin<Box<dyn Future<Output = Result<(), ModerationError>> + Send + 'a>>

Remove all reactions left by user_id on a message.

Errors

Returns ModerationError on API or transport failure.
