Native Rust services

LongHorn can hand heavy computation to a separate native Rust service, reached over a typed, authenticated HTTP protocol. Rust is optional: ordinary TypeScript builds and generated projects do not compile it.

What exists today

• One working service: a report computation service, in native/rust/reports.
• It requires a bearer credential on every route and binds to loopback only.
• A typed client for it was checked from Node, Bun, Deno and workerd.
• It is a separate process, not another JavaScript runtime adapter.

Run the demo

From a clone of the repository, with the pinned Rust toolchain, one command starts the jobs app with Rust computing its reports, using random credentials.

rustup toolchain install 1.97.1 --profile minimal --component rustfmt
pnpm demo:rust-reports

No performance comparison with TypeScript has been published, so this page does not claim one.
