// Throttling is quite complicated. This comment describes the algorithm of the
// current implementation.
//
// ### Request
//
// When a throttling request is sent, it sends a tuple of `ChatId` and
// `Sender<()>` to the worker. Then the request waits for a notification from
// the worker. When notification is received, it sends the underlying request.
//
// ### Worker
//
// The worker does the most important job -- it ensures that the limits are
// never exceeded.
//
// The worker stores a history of requests sent in the last minute (and to which
// chats they were sent) and a queue of pending updates.
//
// The worker does the following algorithm loop:
//
// 1. If the queue is empty, wait for the first message in incoming channel (and
// add it to the queue).
//
// 2. Read all present messages from an incoming channel and transfer them to
// the queue.
//
// 3. Record the current time.
//
// 4. Clear the history from records whose time < (current time - minute).
//
// 5. Count all requests which were sent last second, `allowed =
// limit.messages_per_sec_overall - count`.
//
// 6. If `allowed == 0` wait a bit and `continue` to the next iteration.
//
// 7. Count how many requests were sent to which chats (i.e.: create
// `Map<ChatId, Count>`). (Note: the same map, but for last minute also exists,
// but it's updated, instead of recreation.)
//
// 8. While `allowed >= 0` search for requests which chat haven't exceed the
// limits (i.e.: map[chat] < limit), if one is found, decrease `allowed`, notify
// the request that it can be now executed, increase counts, add record to the
// history.

//
// 1. The work seems not very CPU-bound, it's not heavy computations,
// it's more like light computations.
//
// 2. `spawn_blocking` is not zero-cost — it spawns a new system thread
// + do so other work. This may actually be *worse* then current
// "just do everything in this async fn" approach.
//
// 3. With `rt-threaded` feature, tokio uses [`num_cpus()`] threads
// which should be enough to work fine with one a-bit-blocking task.
// Crucially current behaviour will be problem mostly with
// single-threaded runtimes (and in case you're using one, you
// probably don't want to spawn unnecessary threads anyway).
//
// I think if we'll ever change this behaviour, we need to make it

//! - `cache_me` — enables [`CacheMe`] bot adaptor
//! - `full` — enables all features except `nightly` and tls-related
//! - `nightly` — enables nightly-only features, currently:
//! - Removes some future boxing using `#![feature(type_alias_impl_trait)]`
