ferrosaur

So you use deno_core, and you want to call JavaScript from Rust.

// If you have: lib.js
export const slowFib = (n) =>
  n === 0 ? 0 : n === 1 ? 1 : slowFib(n - 1) + slowFib(n - 2);

// and you write: lib.rs
use ferrosaur::js;

#[js(module("lib.js"))]
struct Math;

#[js(interface)]
impl Math {
    #[js(func)]
    fn slow_fib(&self, n: serde<usize>) -> serde<usize> {}
}

// Then you get:
// let rt: &mut JsRuntime;
let lib = Math::main_module_init(rt).await?;
let fib = lib.slow_fib(42, rt)?;
assert_eq!(fib, 267914296);

ferrosaur derives types and implementations, à la wasm-bindgen, that you can use with your favorite JsRuntime.
