Enum JeNetworkMethod 

pub enum JeNetworkMethod {
    Cartesian,
    A,
}

Method used to construct edges from journal entries when writing graphs/je_network.csv (v5.8.0+).

Reference: Ivertowski (2024), Hardware Accelerated Method for Accounting Network Generation, Methods A through E.

Variants

Cartesian

Method B (full Cartesian product) for every JE — bijective on 2-line entries (Method A) and n × m Cartesian for multi-line entries with proportional amount allocation. Produces O(n × m) edges per JE — a 50-debit / 50-credit period-close consolidation alone yields 2 500 edges, and a typical HF-scale 1 M-line config can blow up to 200 M+ edges (and tens of GB of memory). Use explicitly when downstream consumers already depend on the Cartesian shape.

A

Method A only — emit a single edge per 2-line journal entry (1 debit + 1 credit) and skip multi-line entries entirely. Edge count = number of 2-line JEs (≈ 60 % of entries per the 2024 paper); per-edge confidence is exactly 1.0.

Default since v5.27 (previously Cartesian). The Cartesian default OOM’d small-complexity CLI smoke tests on 14-16 GB CI runners — a 50 × 50 period-close JE alone wanted 20 GB of edge memory. Method A is the bounded, exactness-preserving fallback recommended for published reference datasets where size and exactness matter more than recall on multi-line consolidations. Set je_network.method: cartesian explicitly to restore the pre-v5.27 behaviour.

Trait Implementations

impl Clone for JeNetworkMethod

fn clone(&self) -> JeNetworkMethod

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for JeNetworkMethod

impl Debug for JeNetworkMethod

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for JeNetworkMethod

fn default() -> JeNetworkMethod

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for JeNetworkMethod

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for JeNetworkMethod

impl PartialEq for JeNetworkMethod

fn eq(&self, other: &JeNetworkMethod) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for JeNetworkMethod

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
