Function run_oop_serving 

pub async fn run_oop_serving(
    opts: RunOptions,
    serve: OopServeOptions,
) -> Result<()>

Run an out-of-process gear and serve its HTTP routes.

Uses the same setup as run, then drives the OoP serving lifecycle: lifecycle phases, an Axum HTTP server with framework probes, background self-registration, dependency resolution, and graceful drain.

Errors

Returns an error if discovery, any lifecycle phase, or the HTTP server fails.
