Redoc in Rust

One file, no crates: a TcpListener from the standard library answers every request with the docs page. The Redoc bundle comes from the jsDelivr CDN and the API description from a URL.

Run

cargo run

Then open http://localhost:8080.

Use it in your app

• src/main.rs — the response is a <redoc spec-url> tag plus one script tag. That is all Redoc needs; in a real app the same HTML goes into whatever web framework you use.
• DEFAULT_REDOC_URL is where the bundle is loaded from; the REDOC_URL environment variable overrides it, for self-hosting or pinning another version.
• CAFE is where your API description lives — any URL the browser can fetch.

Docker

docker build -f docker/Dockerfile -t redoc-rust .
docker run --rm -p 8080:8080 redoc-rust
