Struct JeNetworkEdgeBuilder 

pub struct JeNetworkEdgeBuilder { /* private fields */ }

v5.31 C1 Phase 6 — stateful, JE-at-a-time edge builder.

Maintains the line_id → edge_id mapping across push_je calls so cross-JE predecessor chains within an entity (e.g. payment-JE → invoice-JE → PO-JE document chains) resolve correctly even when the caller streams JEs one at a time rather than passing them as a single slice to build_je_network_edges.

Use this when the caller wants to feed JEs from a streaming JSON parse (or other streaming source) without materialising the whole Vec<JournalEntry> in memory. The accumulated edges Vec grows as push_je is called and can be drained at any point via Self::drain_edges.

Equivalent to calling build_je_network_edges with the same JEs passed as one slice — byte-identical output (same edge IDs, same predecessor resolution, same iteration order).

Implementations

impl JeNetworkEdgeBuilder

pub fn new(method: JeNetworkMethod) -> Self

Create a builder with the given method and zero initial capacity.

pub fn with_capacity(method: JeNetworkMethod, capacity: usize) -> Self

Create a builder pre-sized for the expected total edge count.

pub fn push_je(&mut self, je: &JournalEntry)

Process one JE — append its edges to the internal edges vector, resolving predecessor_line_id against the line→edge map built from prior push_je calls.

pub fn drain_edges(&mut self) -> Vec<JeNetworkEdge>

Take the accumulated edges, leaving the builder empty (the line→edge map is also cleared).

pub fn into_edges(self) -> Vec<JeNetworkEdge>

Consume the builder and return the accumulated edges.

pub fn edge_count(&self) -> usize

Current edge count (useful for batched flushes from the streaming caller).
