It looks like these are primarily targeted at informing whether functionality is either on web workers, windows, or both. For now we'll generate the same bindings regardless, and users will need to be proactive about what they're using. In that case there shouldn't be any need for us to process these, so avoid warning about them!
wasm-bindgen
Facilitating high-level interactions between wasm modules and JavaScript.
Introduction blog post: "JavaScript to Rust and Back Again: A wasm-bindgen Tale"
Import JavaScript things into Rust and export Rust things to JavaScript.
src/lib.rs:
#![feature(use_extern_macros, wasm_import_module)]
extern crate wasm_bindgen;
use wasm_bindgen::prelude::*;
// Import the `window.alert` function from the Web.
#[wasm_bindgen]
extern {
fn alert(s: &str);
}
// Export a `greet` function from Rust to JavaScript, that alerts a
// hello message.
#[wasm_bindgen]
pub fn greet(name: &str) {
alert(&format!("Hello, {}!", name));
}
Use exported Rust things from JavaScript!
index.js:
// Asynchronously load, compile, and import the Rust's WebAssembly
// and JavaScript interface.
import("./hello_world").then(module => {
// Alert "Hello, World!"
module.greet("World!");
});
