/// ### `Deno.serve`, but for Gleam!
///
/// `Deno.serve` allows you to create a server using the web standard
/// [`Request`](https://developer.mozilla.org/en-US/docs/Web/API/Request) and
/// [`Response`](https://developer.mozilla.org/en-US/docs/Web/API/Response) types.
/// Stego translates between these types and Gleam's own
/// [`Request`](https://hexdocs.pm/gleam_http/gleam/http/request.html) and
/// [`Response`](https://hexdocs.pm/gleam_http/gleam/http/response.html) types.
/// Your response body can be a `BitArray`, `String`, or `StringBuilder`.
