ferrosaur

ferrosaur derives statically-typed Rust code — à la wasm-bindgen — for deno_core::JsRuntime to interface with your JavaScript code.

You have:

// lib.js
export const add = (a, b) => a + b;

You write:

// lib.rs
#[js(module("lib.js"))]
struct Module;

#[js(interface)]
impl Module {
    #[js(func)]
    fn add(&self, a: serde<f64>, b: serde<f64>) -> serde<f64> {}
}

You get:

// let rt: &mut JsRuntime;
let module = Module::main_module_init(rt).await?;
let result = module.add(66.0, 3.0)?;

[!TIP]

This is like the inverse of deno_core::op2:

• #[op2] gives JavaScript programs easy access to your Rust implementation.
• ferrosaur gives your Rust program easy access to JavaScript implementations.
