Enum GraphRouting 

pub enum GraphRouting {
    Single {
        handle: Arc<GraphHandle>,
    },
    Multi {
        registry: Arc<GraphRegistry>,
        config_path: Option<PathBuf>,
    },
}

Runtime routing for the server. Single mode = legacy omnigraph-server <URI> invocation, one graph, flat HTTP routes. Multi mode = --config omnigraph.yaml with a non-empty graphs: map, N graphs, cluster routes (/graphs/{graph_id}/...). Mode is determined at startup by load_server_settings.

In single mode the handle lives here directly — there is no registry, no sentinel key, no walk-and-assert. In multi mode the registry carries N handles and the middleware dispatches on the URL’s {graph_id} segment.

Both modes share the same handler bodies — the routing middleware (resolve_graph_handle) injects Arc<GraphHandle> as a request extension so handlers never see the routing discriminator.

Variants

Single

Single-graph deployment: one handle, flat routes (/snapshot, /read, …). The handle.uri field carries the URI the engine was opened from. Backward compatible with v0.6.0 deployments.

Fields

handle: Arc<GraphHandle>

Multi

Multi-graph deployment: many handles, cluster routes (/graphs/{graph_id}/...). config_path is the omnigraph.yaml the server reads at startup; preserved here so future runtime mutation (deferred) can find the source of truth without re-parsing CLI args. The server treats the file as operator-owned and never writes it.

Fields

registry: Arc<GraphRegistry>

config_path: Option<PathBuf>
