🚀 Oak JSON Parser

The Foundation of Data Exchange — A high-performance, incremental JSON parser built on the Oak framework. Optimized for large-scale data processing, configuration management, and real-time validation.

🎯 Project Vision

JSON is the universal language of data exchange in modern computing. oak-json provides a high-performance, Rust-powered infrastructure for parsing and analyzing JSON data. By leveraging Oak's incremental parsing architecture, it enables developers to build tools that can handle massive JSON files and streams with sub-millisecond latency, making it ideal for everything from configuration editors to large-scale data analysis pipelines.

✨ Core Features

• ⚡ Blazing Fast: Fully utilizes Rust's performance advantages to deliver sub-millisecond parsing response times, even for deeply nested JSON structures.
• 🔄 Incremental Parsing: Built-in support for partial updates—re-parse only the parts of the JSON that changed, significantly improving performance for large configuration files.
• 🌳 High-Fidelity AST: Generates a clear and easy-to-traverse Abstract Syntax Tree capturing:
  • Objects, Arrays, and nested structures
  • Precise tracking of keys and values
  • Full support for all JSON data types (Strings, Numbers, Booleans, Null)
• 🛡️ Industrial-Grade Error Recovery: Engineered to handle malformed or incomplete JSON gracefully, providing precise diagnostics to help developers and users fix data issues quickly.
• 🧩 Ecosystem Integration: Seamlessly works with other Oak tools for validation, formatting, and semantic analysis.

🏗️ Architecture

The parser follows the Green/Red Tree architecture (inspired by Roslyn), which allows for:

1. Efficient Immutability: Share nodes across different versions of the tree without copying.
2. Lossless Syntax Trees: Retains all trivia (whitespace and comments, if applicable in extended JSON formats), enabling faithful code formatting and refactoring.
3. Type Safety: Strongly-typed "Red" nodes provide a convenient and safe API for tree traversal and analysis.
