# Callback Macro

This is a tag for annotating Rust functions that should be used as callbacks in
JavaScript using the kaja-web framework.

Example usage:
```rust
use kaja_html_macro;
use kaja_web::prelude::*;

#[derive(serde::Deserialize)]
struct SomeClickEvent {
    index: usize,
}

#[callback("someClickCallback")]
fn some_on_click_function(event: SomeClickEvent) {
    log!("event.index: {:?}", event.index);
}

pub fn example() -> String {
    // This example allows you to call the Rust function from JavaScript like this:
    let html = html! {{
        <button onclick="someClickCallback({
            index: 1
        })">Run WASM Callback</button>
    }};

    html
}

#[wasm_bindgen(start)]
pub fn init() {
    // make the callbacks available to JavaScript
    init_callbacks(); 
}
```
