# event-notify


<!-- Badges placeholder -->


English | [简体中文](./README-CN.md)

*event-notify* provides a lightweight event listener/notification chain implementation. Create events with chained listeners where each listener can process or forward the event.

No external dependencies required — pure Rust standard library.

## Features


- Lightweight event listener pattern
- Chained listeners via `Next` forwarding
- Fire events with arbitrary payload and return types
- Zero dependencies

## Cargo Feature Flags


This crate has no Cargo feature flags. All functionality is enabled by default.

## Basic Usage


```rust
use event_notify::Event;

let event = Event::<i32, i32>::listen(|args, _next| {
    args * 2
}).finish();

let result = event.fire(21);
assert_eq!(result, 42);
```

## Tests


```bash
cargo test -p event-notify
```

7 tests covering single listener, chained listeners, chain break, and multiple fire scenarios.
