Function try_run_mesh_host

pub fn try_run_mesh_host<U, F, T>(base_name: &str, f: F) -> Result<()>
where
    U: 'static + MeshPayload + Send,
    F: AsyncFnOnce(U) -> Result<T>,

Runs a mesh host in the current thread, then exits the process, if this process was launched by Mesh::launch_host.

The mesh invitation is provided via environment variables. If a mesh invitation is not available this function will return immediately with Ok. If a mesh invitation is available, this function joins the mesh and runs the future returned by f until f returns or the parent process shuts down the mesh.
