• 🔒 Type Safe — Comprehensive, modern C++20 type system
• 🌐 Multi-Language — Language bindings for Python, Node.js, JavaScript, Go, and PHP
• 🎯 Zero-Copy Decoding — Efficient std::span API for minimal allocations
• 📝 Schema Validation — Validate data against user-defined schemas
• 🌊 Streaming API — Efficiently encode and decode sequences of objects

• btoon-core — C++20 core library with C-API for language bindings

• btoon-python — Python bindings (pybind11)
• btoon-nodejs — Node.js bindings (N-API)
• btoon-javascript — JavaScript/WASM bindings
• btoon-go — Go bindings (cgo)
• btoon-php — PHP bindings

#include "btoon/btoon.h"

using namespace btoon;

// Create a value
Value data = Map{
    {"name", String("Alice")},
    {"age", Int(30)},
    {"active", Bool(true)}
};

// Encode
auto encoded = encode(data);

// Decode
auto decoded = decode(encoded);
