Crate llm_json

LLM JSON Repair

A Rust library to repair broken JSON strings, particularly useful for handling malformed JSON output from Large Language Models (LLMs).

This is a porting of the Python library json_repair (https://github.com/mangiucugna/json_repair), written by Stefano Baccianella (https://github.com/mangiucugna) and published under the MIT license. All credits go to the original author for the amazing work.

Features

• Fix missing quotes around keys and values
• Handle misplaced commas and missing brackets
• Repair incomplete arrays and objects
• Remove extra non-JSON characters
• Auto-complete missing values with sensible defaults
• Preserve Unicode characters

Usage

use llm_json::{repair_json, loads, JsonRepairError};

// Basic repair
let broken_json = r#"{name: 'John', age: 30,}"#;
let repaired = repair_json(broken_json, &Default::default()).unwrap();
println!("{}", repaired); // {"name": "John", "age": 30}

// Parse directly to Value
let value = loads(broken_json, &Default::default()).unwrap();
