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