rusty_esm
This is an example showcasing a common use case for embedding Deno - calling JS module exports from Rust. The rest is pretty self explainatory:
// main.rs
#[derive(Debug, Deserialize)]
struct ApiResponse {
user_id: isize,
id: isize,
title: String,
completed: bool,
}
let mut rt = Runtime::new("testdata/basic.js").await?;
let id = 5;
let value: ApiResponse = rt.call("getStuff", &[id]).await?;// testdata/basic.js
export async function getStuff(id) {
const r = await fetch("https://jsonplaceholder.typicode.com/todos/" + id);
return await r.json();
}$ target/debug/deno_embed
ApiResponse {
user_id: 0,
id: 5,
title: "laboriosam mollitia et enim quasi adipisci quia provident illum",
completed: false,
}Benchmarks
Measured for Runtime::call in example scenarios. See src/main.rs.
