Detailed Description

Zero-copy value view for efficient data access.

This header provides value_view class for zero-copy access to serialized data. Instead of copying values during deserialization, value_view points directly into the original buffer, providing significant performance improvements for large messages.

Usage:

auto container = std::make_shared<value_container>(large_data, true);
 
// Zero-copy access (no allocation)
if (auto view = container->get("large_text", as_view)) {
    std::string_view text = view->as_string_view();
    // Use text without copying...
 
    // Copy only when needed
    std::string owned = view->as_string();
}
