Struct FlowNetwork 

pub struct FlowNetwork { /* private fields */ }

A network oriented by flow direction.

Built from a connection graph plus ports, because direction lives on the port and connectivity lives on the relationship. Neither alone is enough.

Implementations

impl FlowNetwork

pub fn build(graph: &ConnectionGraph, ports: &[Port]) -> Self

Orient a connection graph using the ports’ flow directions.

pub fn query(&self, element: EntityId, direction: Direction) -> FlowQuery

Elements reachable from element following (or opposing) flow.

Cycle-safe: a ring main revisits elements, and the visited set is what makes this terminate. Ring mains are normal topology, not corruption.

pub fn downstream_of(&self, element: EntityId) -> FlowQuery

What this element feeds.

pub fn upstream_of(&self, element: EntityId) -> FlowQuery

What feeds this element.
