ffsshhttiikk What I do
- Write WebAssembly modules
- Use Rust/AssemblyScript for WASM
- Integrate WASM in web apps
- Optimize performance-critical code
When to use me
When needing near-native performance in browsers.
Rust to WASM
#[no_mangle]
pub extern "C" fn add(a: i32, b: i32) -> i32 {
a + b
}
// Load WASM
const wasm = await WebAssembly.instantiateStreaming(
fetch('add.wasm')
);
wasm.instance.exports.add(1, 2); // 3
JavaScript WASM Loading
async function loadWasm(url) {
const response = await fetch(url);
const buffer = await response.arrayBuffer();
const wasm = await WebAssembly.instantiate(buffer);
return wasm.instance.exports;
}
