// The `--no-modules`-generated JS from `wasm-bindgen` attempts to use
|
|
// `WebAssembly.instantiateStreaming` to instantiate the wasm module,
|
|
// but this doesn't work with `file://` urls. This example is frequently
|
|
// viewed by simply opening `index.html` in a browser (with a `file://`
|
|
// url), so it would fail if we were to call this function!
|
|
//
|
|
// Work around this for now by deleting the function to ensure that the
|
|
// `no_modules.js` script doesn't have access to it. You won't need this
|
|
// hack when deploying over HTTP.
