// A compiler experiment: a Nikaia program calls a Rust crate that starts its
// own threads and event loop, serves one HTTP request, and hands a `String` to
// one of those threads.
//
//     cd examples/foreign-runtime/serve
//     nikaia run
//
// It is meant to print:
//
//     served: GET /hello on tokio-rt-worker
//     crossed: a String is Send on tokio-rt-worker, called from main
//
// The literal reaches Rust as a `String`: `across_a_thread`'s `T` is decided
// by this argument alone, and a text literal is `String`. The first build
// fetches `hyper` and `tokio` from crates.io.
//
// It checks that this works at all. Nothing in the source shows that the calls
// start threads, and nothing in the language lets it say so.
