index_keystd::array<uint8_t, 32>32-byte encryption key for the index, used to secure index data.
max_cache_sizestd::optional<size_t>(Optional) Maximum size for the local cache (default is 0).
loggercyborg::Logger*(Optional) Pointer to a logger instance for capturing operation logs (default is nullptr).

Example Usage

#include "cyborgdb_core/client.hpp"
#include "cyborgdb_core/encrypted_index.hpp"
#include "cyborgdb_core/logger.hpp"
#include <array>

// ... Initialize the client ...

// Create a secure 32-byte key (example: all zeros)
std::array<uint8_t, 32> index_key = {0};

// Optional: Create and configure a logger
cyborg::Logger logger;
logger.Configure(LogLevel::Debug, true, "index_loading.log");

auto index = client.LoadIndex("my_index", index_key, 1000, &logger);
