Struct JsonFormat 

pub struct JsonFormat {
    pub pretty: bool,
}

Custom JSON format handler.

This format preserves all narrative structure and metadata, making it ideal for storing narratives in databases or exchanging between systems.

Example

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

let format = JsonFormat::new();

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

let narrative = Narrative::builder()
    .title("My Story")
    .event(event)
    .build();

let json = format.export_str(&narrative).unwrap();
let restored = format.import_str(&json).unwrap();

assert_eq!(restored.events().len(), 1);

Fields

pretty: bool

Whether to pretty-print the JSON output
