Crate ison_rs 

ISON Parser for Rust

A Rust implementation of the ISON (Interchange Simple Object Notation) parser. ISON is a minimal, LLM-friendly data serialization format optimized for AI/ML workflows.

Quick Start

use ison_rs::{parse, dumps, Value};

let ison_text = r#"
table.users
id name email
1 Alice alice@example.com
2 Bob bob@example.com
"#;

let doc = parse(ison_text).unwrap();
let users = doc.get("users").unwrap();

for row in &users.rows {
    println!("{}: {}", row.get("id").unwrap(), row.get("name").unwrap());
}

// Serialize back
let output = dumps(&doc, true);
