Struct TemporalIndex 

pub struct TemporalIndex {
    pub min_date: Option<NaiveDate>,
    pub max_date: Option<NaiveDate>,
    /* private fields */
}

Index for efficient temporal queries on graph edges.

Fields

min_date: Option<NaiveDate>

Minimum date in the index.

max_date: Option<NaiveDate>

Maximum date in the index.

Implementations

impl TemporalIndex

pub fn build(graph: &Graph) -> Self

Builds a temporal index from a graph. Complexity: O(E log E) for sorting edges by date.

pub fn edges_in_range( &self, node_id: NodeId, start: NaiveDate, end: NaiveDate, ) -> Vec<(NaiveDate, EdgeId)>

Returns edges for a node within a date range (inclusive).

pub fn edges_for_node(&self, node_id: NodeId) -> &[(NaiveDate, EdgeId)]

Returns all edges for a node, sorted by date.

pub fn node_count(&self) -> usize

Returns the number of nodes with temporal data.

Trait Implementations

impl Clone for TemporalIndex

fn clone(&self) -> TemporalIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TemporalIndex

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

Formats the value using the given formatter.
