Module run_wasm 

cargo xtask run-wasm: build and serve the web examples.

The pipeline is the standard one for a wasm32-unknown-unknown binary a browser runs: build for the target, hand the wasm to wasm-bindgen so it gets a JS loader, then put the pages and the wasm behind a static file server — WebGPU is only available in a secure context, and localhost is one, while a file:// URL is not. The server is built in (super::http), so nothing needs to be installed.

The output directory is the one the Pages workflow publishes: a landing page at the root, one directory per example beside it, and the API docs under docs/ — which only the workflow builds. --app picks which examples are built; the landing page links the ones that are there.

Structs

Example

One example the site can show.

Constants

DOCS_DIR 🔒

Where the API docs sit under the site’s root.

EXAMPLES

Every example the site can show, in the order the landing page lists them.

EXAMPLE_HTML 🔒

The page that starts one example.

LANDING_HTML 🔒

The site’s landing page: what the examples are, and where the docs are.

OUT_DIR

Where the bindgen output lands, inside target/.

PORT 🔒

The port the site prefers to be served on. Fixed, so the URL to open is predictable; if it is taken, the server tries the ports after it.

PROFILE

The cargo profile every wasm build of this repository uses, defined in the workspace manifest: release’s settings at a size-oriented opt-level, the trade-off the name keeps from the wasm-dev it was renamed from — wasm builds are only ever made for a browser to download, so none of them pay for the larger binary --release produces.

TARGET

The target triple the web build runs on.
