Making keyboard events management in [WASM] with [web-sys] easier.

Usage

Add this to your Cargo.toml:

toml [dependencies] wasm_keyboard = "0.1"

Example

```rust,ignore use std::rc::Rc;

use wasmbindgen::prelude::*; use wasmkeyboard::{ macros::{newsimplifiedkeyhandler, startkeywisekeyboardhandler}, uieventscode::{KeyboardEventCode, KEYW}, }; use web_sys::KeyboardEvent;

// Called when the wasm module is instantiated

[wasm_bindgen(start)]

fn main() -> Result<(), JsValue> { // Use web_sys's global window function to get a handle on the global // window object. let window = web_sys::window().expect("no global window exists"); let document = Rc::new(window.document().expect("should have a document on window")); let body = Rc::new(document.body().expect("document should have a body"));

let w_handler = new_simplified_key_handler!(
    KeyboardEventCode::KeyW,
    state = (),
    keydown = {
        let body = body.clone();
        let document = document.clone();
        move |_state| {
            let val = document.create_element("p").unwrap();
            val.set_inner_html("W pressed down!");
            body.append_child(&val).unwrap();
        }
    },
    keyup = {
        let body = body.clone();
        let document = document.clone();
        move |_state| {
            let val = document.create_element("p").unwrap();
            val.set_inner_html("W released!");
            body.append_child(&val).unwrap();
        }
    }
);

start_keywise_keyboard_handler!(kh: Kh, document, [KEY_W => w_handler]);

// Manufacture the element we're gonna append
let val = document.create_element("p")?;
val.set_inner_html("Hello from Rust!");

body.append_child(&val)?;

Ok(())

} ```
