比如在io/async/AsyncSocket.h中,根据条件的不同使用small_vector或者std::vector: // Lifecycle observers./// Use small_vector to avoid heap allocation for up to two observers, unless// mobile, in which case we fallback to std::vector to prioritize code size.usingLifecycleObserverVecImpl =condit...

// Helper: Lightweight std::vector<> like class to avoid dragging dependencies// (also: Windows implementation of STL with debug enabled is absurdly slow,// so let's bypass it so our code runs fast in debug).// *Important* Our implementation does NOT call C++ constructors/destructors.//...
