//! # Event Bus
|
||||
//!
|
||||
//! An asynchronous event bus for routing typed messages between modules
|
||||
//! without direct coupling.
|
||||
//!
|
||||
//! ## Features
|
||||
//!
|
||||
//! - **Key → event mapping**: each topic (`&str`) is independent
|
||||
//! - **Type-unrestricted**: any `T: Any + Send + Sync + Clone`
|
||||
//! - **Targeted wake-up**: only subscribers of the matching topic are woken up
|
||||
//! - **Callback API**: JavaScript-style — `bus.on("topic", |payload| { ... })`
|
||||
//! - **Glob pattern**: `on_pattern("user-*", |topic, payload| { ... })`
|
||||
//! - **Async handlers**: `on_async` and `on_pattern_async`
|
||||
//!
|
||||
//! ## Example — sync callback
|
||||
//!
|
||||
//! ```rust,no_run
|
||||
//! use std::sync::Arc;
|
||||
//! use oxspeak_server_lib::event_bus::EventBus;
|
||||
//!
|
||||
//! #[derive(Clone, Debug)]
|
||||
//! struct User { name: String }
|
||||
//!
|
||||
//! # tokio_test::block_on(async {
|
||||
//! let bus = Arc::new(EventBus::new());
|
||||
//!
|
||||
//! bus.on::<User>("user-connected", |user| {
|
||||
//! println!("Connected: {:?}", user);
|
||||
//! });
|
||||
//!
|
||||
//! bus.emit("user-connected", User { name: "Alice".into() });
|
||||
//! # tokio::time::sleep(std::time::Duration::from_millis(10)).await;
|
||||
//! # });
|
||||
//! ```
|
||||
//!
|
||||
//! ## Example — async callback
|
||||
//!
|
||||
//! ```rust,no_run
|
||||
//! use std::sync::Arc;
|
||||
//! use oxspeak_server_lib::event_bus::EventBus;
|
||||
//!
|
||||
//! #[derive(Clone, Debug)]
|
||||
//! struct User { name: String }
|
||||
//!
|
||||
//! # tokio_test::block_on(async {
|
||||
//! let bus = Arc::new(EventBus::new());
|
||||
//!
|
||||
//! bus.on_async::<User, _, _>("user-connected", |user| async move {
|
||||
//! println!("(async) Connected: {:?}", user);
|
||||
//! });
|
||||
//!
|
||||
//! bus.emit("user-connected", User { name: "Bob".into() });
|
||||
//! # tokio::time::sleep(std::time::Duration::from_millis(10)).await;
|
||||
//! # });
|
||||
//! ```
|
||||
//!
|
||||
//! ## Example — glob pattern (topic included in the callback)
|
||||
//!
|
||||
//! ```rust,no_run
|
||||
//! use std::sync::Arc;
|
||||
//! use oxspeak_server_lib::event_bus::EventBus;
|
||||
//!
|
||||
//! #[derive(Clone, Debug)]
|
||||
//! struct User { name: String }
|
||||
//!
|
||||
//! # tokio_test::block_on(async {
|
||||
//! let bus = Arc::new(EventBus::new());
|
||||
//!
|
||||
//! bus.on_pattern::<User, _>("user-*", |topic, user| {
|
||||
//! match topic.as_str() {
|
||||
//! "user-created" => println!("Created : {:?}", user),
|
||||
//! "user-deleted" => println!("Deleted : {:?}", user),
|
||||
//! other => println!("{}: {:?}", other, user),
|
||||
//! }
|
||||
//! });
|
||||
//!
|
||||
//! bus.emit("user-created", User { name: "Alice".into() });
|
||||
//! bus.emit("user-deleted", User { name: "Bob".into() });
|
||||
//! # tokio::time::sleep(std::time::Duration::from_millis(10)).await;
|
||||
//! # });
|
||||
//! ```
|
||||
//!
|
||||
//! ## Example — multi-type with `match_event!` (advanced)
|
||||
//!
|
||||
//! ```rust,no_run
|
||||
//! use std::sync::Arc;
|
||||
//! use oxspeak_server_lib::event_bus::EventBus;
|
||||
//! use oxspeak_server_lib::match_event;
|
||||
//!
|
||||
//! #[derive(Clone, Debug)] struct User { name: String }
|
||||
//! #[derive(Clone, Debug)] struct UdpMetric { value: f32 }
|
||||
//!
|
||||
//! # tokio_test::block_on(async {
|
||||
//! let bus = Arc::new(EventBus::new());
|
||||
//! let mut rx = bus.on_raw("mixed-topic");
|
||||
//!
|
||||
//! bus.emit("mixed-topic", User { name: "Alice".into() });
|
||||
//!
|
||||
//! if let Ok(evt) = rx.recv().await {
|
||||
//! match_event!(evt,
|
||||
//! User => |u| println!("User: {:?}", u),
|
||||
//! UdpMetric => |m| println!("Metric: {:?}", m),
|
||||
//! );
|
||||
//! }
|
||||
//! # });
|
||||
//! ```
