// 综合测试成绩:
// CRTP: -O0->6629 µs, -O2->88 µs
// std::variant: -O0->35229 µs, -O2->373 µs
// Type Erasure: -O0->23404 µs, -O2->3712 µs
// ECS: -O0->23662 µs, -O2->2847 µs
// Virtual Function: -O0->20982 µs, -O2->6044 µs

// -O0: CRTP > Virtual Function > Type Erasure ~= ECS > std::variant
// -O2: CRTP > std::variant > ECS > Type Erasure > Virtual Function


// 综合考虑，引擎采用CRTP多态实现方法。
