Module index 

Spatial and temporal indexing for efficient queries.

This module provides data structures for fast spatial and temporal lookups of events and other entities.

Overview

• SpatialIndex - R-tree based spatial indexing for geographic queries
• TemporalIndex - B-tree based temporal indexing for time-range queries
• SpatiotemporalIndex - Combined space-time indexing

Example

use spatial_narrative::index::{SpatialIndex, TemporalIndex, SpatiotemporalIndex};
use spatial_narrative::core::{Location, Timestamp, GeoBounds, TimeRange};

// Create a spatiotemporal index
let mut index = SpatiotemporalIndex::new();

index.insert("Event 1",
    &Location::new(40.7128, -74.0060),
    &Timestamp::now());

// Query by location
let bounds = GeoBounds::new(39.0, -75.0, 42.0, -73.0);
let spatial_results = index.query_spatial(&bounds);

// Query by time
let range = TimeRange::year(2024);
let temporal_results = index.query_temporal(&range);

// Query by both
let combined_results = index.query(&bounds, &range);
