Struct StarTopologyScore 

pub struct StarTopologyScore {
    pub min_degree: usize,
    /* private fields */
}

Star topology score kernel.

Detects and scores star/hub-and-spoke topology patterns. Critical for AML (smurfing detection) and fraud (money mule identification).

Fields

min_degree: usize

Minimum degree to be considered a potential hub.

Implementations

impl StarTopologyScore

pub fn new() -> Self

Create a new star topology score kernel.

pub fn with_min_degree(min_degree: usize) -> Self

Create with custom minimum degree threshold.

pub fn compute_single( graph: &CsrGraph, in_degrees: Option<&[u32]>, node: usize, min_degree: usize, ) -> StarTopologyResult

Compute star topology score for a single node.

pub fn compute_batch(&self, graph: &CsrGraph) -> Vec<StarTopologyResult>

Compute star topology scores for all nodes.

pub fn top_k_hubs(&self, graph: &CsrGraph, k: usize) -> Vec<StarTopologyResult>

Find top-K star hubs.

pub fn find_in_stars( &self, graph: &CsrGraph, min_score: f64, ) -> Vec<StarTopologyResult>

Find in-star hubs (collection accounts).

pub fn find_out_stars( &self, graph: &CsrGraph, min_score: f64, ) -> Vec<StarTopologyResult>

Find out-star hubs (distribution accounts - potential smurfing).
