Struct SnapshotGraph 

pub struct SnapshotGraph {
    pub snapshots: Vec<GraphSnapshot>,
    pub time_window: Option<f64>,
}

Sequence of graph snapshots forming a temporal graph.

Fields

snapshots: Vec<GraphSnapshot>

Ordered list of snapshots.

time_window: Option<f64>

Optional time-window width used when building snapshots.

Implementations

impl SnapshotGraph

pub fn new() -> Self

Create an empty snapshot graph.

pub fn with_time_window(self, window: f64) -> Self

Attach a time-window parameter.

pub fn add_snapshot(&mut self, snapshot: GraphSnapshot)

Insert a snapshot, maintaining chronological order.

pub fn n_snapshots(&self) -> usize

Number of snapshots.

pub fn snapshot_at(&self, t: f64) -> Option<&GraphSnapshot>

Get the snapshot whose timestamp is closest to t.

pub fn all_nodes(&self) -> Vec<usize>

All unique node identifiers across all snapshots.

pub fn temporal_degree(&self, node: usize) -> Vec<(f64, usize)>

Temporal degree sequence: (time, degree) for every snapshot.

pub fn burstiness(&self, src: usize, dst: usize) -> f64

Burstiness coefficient B = (σ-μ)/(σ+μ) for inter-event times of edge (src,dst).

Returns 0.0 when there are fewer than two activations.

pub fn temporal_correlation(&self, lag: usize) -> f64

Graph-level temporal autocorrelation (Jaccard similarity of edge sets at lag lag).

Trait Implementations

impl Clone for SnapshotGraph

fn clone(&self) -> SnapshotGraph

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotGraph

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

Formats the value using the given formatter.

impl Default for SnapshotGraph

fn default() -> Self

Returns the “default value” for a type.
