Module io 

Import and export of narratives in various formats.

This module provides converters for reading and writing narratives in standard geographic data formats.

Supported Formats

• GeoJsonFormat - Standard geographic data format
• CsvFormat - Tabular data with configurable columns
• JsonFormat - Custom JSON format optimized for narratives
• GPX - GPS exchange format (optional feature, TODO)

Example

use spatial_narrative::io::{GeoJsonFormat, CsvFormat, JsonFormat, Format};
use spatial_narrative::prelude::*;

let narrative = Narrative::builder()
    .title("My Story")
    .event(Event::builder()
        .location(Location::new(40.7128, -74.006))
        .timestamp(Timestamp::now())
        .text("Something happened")
        .build())
    .build();

// Export to GeoJSON
let geojson_format = GeoJsonFormat::new();
let geojson = geojson_format.export_str(&narrative).unwrap();

// Export to CSV
let csv_format = CsvFormat::new();
let csv = csv_format.export_str(&narrative).unwrap();

// Export to custom JSON
let json_format = JsonFormat::pretty();
let json = json_format.export_str(&narrative).unwrap();
