Function to_registry

document/graph-storage/src/tests/round_trip.rs:25–29

Convert a runtime network to a storage `Registry`, returning the declarations alongside it. Proto-node declaration content is no longer stored in the registry (it lives in a byte store); these tests have no byte store, so they keep the extracted bytes in hand and rebuild a `Declarations` map for the back-conversion.

(network: &NodeNetwork)

/// these tests have no byte store, so they keep the extracted bytes in hand and rebuild a
/// `Declarations` map for the back-conversion.
fn to_registry(network: &NodeNetwork) -> (Registry, crate::Declarations) {
	let conversion = Registry::convert_from_runtime(network, &crate::NoMetadata, &Default::default(), PeerId(0)).expect("Failed to convert NodeNetwork to Registry");
	let declarations = conversion.declarations().expect("rebuild declarations");
	(conversion.registry, declarations)
}

/// A one-node network whose single node references `id` via a `TaggedValue::Resource` input, so
/// `convert_resources` (which only snapshots network-referenced resources) carries the resource.
