/// ## How it works
///
/// Long polling works by repeatedly calling [`Bot::get_updates`][get_updates].
/// If telegram has any updates, it returns them immediately, otherwise it waits
/// until either it has any updates or `timeout` expires.
///
/// Each [`get_updates`][get_updates] call includes an `offset` parameter equal
/// to the latest update id + one, that allows to only receive updates that has
/// not been received before.
///
/// When telegram receives a [`get_updates`][get_updates] request with `offset =
/// N` it forgets any updates with id < `N`. When `polling` listener is stopped,
/// it sends [`get_updates`][get_updates] with `timeout = 0, limit = 1` and
/// appropriate `offset`, so future bot restarts won't see updates that were
/// already seen.
///
/// Consumers of a `polling` update listener then need to repeatedly call
/// [`futures::StreamExt::next`] to get the updates.
///
/// Here is an example diagram that shows these interactions between consumers
/// like [`Dispatcher`], `polling` update listener and telegram.
///
/// ```mermaid
