// JS
function hello() {
let result = fibonacci(10000);
console.log(result);
return result;
}
// Neon
fn hello(mut cx: FunctionContext) -> JsResult<JsNumber> {
let result = cx.number(fibonacci(10000));
println!("{}", result);
Ok(result)
}
Simple Tooling
No makefiles. No fancy global build requirements. Just Node and Rust
Guaranteed Safety
If a neon module compiles, it is guaranteed to be memory safe by the rust compiler
Easy Parallelism
Safely run multiple threads without data races
fn make_an_array(mut cx: FunctionContext) -> JsResult<JsArray> {
// Create some values:
let n = cx.number(9000);
let s = cx.string("hello");
let b = cx.boolean(true);
// Create a new array:
let array: Handle<JsArray> = cx.empty_array();
// Push the values into the array:
array.set(&mut cx, 0, n)?;
array.set(&mut cx, 1, s)?;
array.set(&mut cx, 2, b)?;
// Return the array:
Ok(array)
}
register_module!(mut cx, {
// Export the Rust function as a JS function
cx.export_function("makeAnArray", make_an_array)
})
