The #[wasm_bindgen] attribute can be used on extern "C" { .. } blocks to import functionality from JS. This is how the js-sys and the web-sys crates are built, but you can also use it in your own crate!
For example if you're working with this JS file:
// defined-in-js.js {{#include ../../../examples/import_js/crate/defined-in-js.js}}
you can use it in Rust with:
{{#include ../../../examples/import_js/crate/src/lib.rs}}
