Advanced Design Guide

This directory contains three design guides for the OnceCallback component, intended for readers with C++ template experience. If you are not yet familiar with concepts like move semantics, template partial specialization, or type erasure, we recommend reading the prerequisite articles in the full/ directory first.

• Design Guide 2: Step-by-Step Implementation
• Design Guide 3: Testing Strategy and Performance Comparison
