network_node.move (primitive)

The network_node.move module is a Layer 1 Composable Primitive that manages energy distribution networks within EVE Frontier. It enables assemblies to connect to power sources and facilitates the flow of energy across structures.

1. Core Component Architecture

The module defines the relationship between energy-producing structures and energy-consuming assemblies.

Key Data Structures

• NetworkNode: A storeable struct embedded within assemblies that require power. It tracks:
  • energy_source_id: The ID of the connected EnergySource.
  • is_connected: A boolean indicating whether the node is actively drawing power.

2. Role in the Architecture

Network nodes serve as the “power cables” of the EVE Frontier universe, linking energy producers to consumers.

    end

• Energy Reservation: When an assembly goes online, its NetworkNode calls the energy.move primitive to reserve the required power from the connected source.
• Energy Release: When the assembly goes offline, the reserved energy is released back to the source.

3. Integration with Assemblies

As a Layer 1 Primitive, network_node is composed into Layer 2 Assemblies to enable power connectivity.

• Connection: An assembly’s NetworkNode is connected to an EnergySource during deployment or configuration.
• Validation: Before an assembly can go online, the system verifies that the NetworkNode is connected and the energy source has sufficient available capacity.

4. Security and Access Patterns

• Package-Level Encapsulation: Like other primitives, mutation functions are public(package), ensuring only authorized assemblies can modify connection states.
• Event Emission: Connection and disconnection events are emitted for off-chain tracking of the power grid topology.
