Struct CsvFormat 

pub struct CsvFormat {
    pub options: CsvOptions,
}

CSV format handler.

This format handler can import and export narratives in CSV format. The CSV must have latitude, longitude, and timestamp columns at minimum.

Example

use spatial_narrative::io::{CsvFormat, Format};

let format = CsvFormat::default();

let csv_data = "lat,lon,timestamp,text\n\
                40.7128,-74.006,2024-01-15T14:30:00Z,Something happened\n\
                34.0522,-118.2437,2024-01-16T10:00:00Z,Another event";

let narrative = format.import_str(csv_data).unwrap();
assert_eq!(narrative.events().len(), 2);
