//! A pure-Rust actor framework built on top of the [Tokio](https://tokio.rs) async runtime,
//! inspired by Alice Ryhl's [Actors with Tokio](https://ryhl.io/blog/actors-with-tokio/).
//!
//! `acktor` builds on the patterns described in Alice Ryhl's blog post and extends them into a
//! structured library. Each actor runs as an independent `tokio` task with its own mailbox,
//! processing messages one at a time. Actors communicate exclusively through message passing —
//! there is no shared mutable state. The framework provides lifecycle hooks, supervision, an
//! observer pattern, and support for periodic tasks.
//!
//! # Quick Start
//!
//! An example `Counter` actor that handles arithmetic messages might be the following:
//!
//! ```rust
//! use acktor::{Actor, Context, Handler, Message, Signal};
//!
//! #[derive(Debug)]
//! struct Counter(i64);
//!
//! impl Actor for Counter {
//! type Context = Context<Self>;
//! type Error = String;
//! }
//!
//! #[derive(Debug, Message)]
//! #[result_type(i64)]
//! enum CounterMsg {
//! Increment,
//! Get,
//! }
//!
//! impl Handler<CounterMsg> for Counter {
//! type Result = i64;
//!
//! async fn handle(&mut self, msg: CounterMsg, _ctx: &mut Self::Context) -> i64 {
//! match msg {
//! CounterMsg::Increment => self.0 += 1,
//! CounterMsg::Get => {}
//! }
//! self.0
//! }
//! }
//!
//! async fn run() {
//! let (addr, handle) = Counter(0).run("counter").unwrap();
//!
//! // fire-and-forget
//! addr.do_send(CounterMsg::Increment).await.unwrap();
//!
//! // request-reply
//! let result = addr.send(CounterMsg::Get).await.unwrap().await.unwrap();
//! println!("Counter: {result}"); // Counter: 1
//!
//! addr.do_send(Signal::Stop).await.unwrap();
//! handle.await.unwrap();
//! }
//! ```
//!
//! # Feature Flags
//!
//! | Feature | Default | Description |
//! |---------|---------|-------------|
//! | `derive` | Yes | Enables `#[derive(Message)]` and `#[derive(MessageResponse)]` macros. |
//! | `tokio-tracing` | No | Names spawned actor tasks for [`tokio-console`](https://docs.rs/console-subscriber). Requires building with `RUSTFLAGS="--cfg tokio_unstable"`. |
//! | `bottleneck-warning` | No | Emits `tracing::debug!` logs when an observer's mailbox is full during notification, useful for spotting slow consumers. |
