template<typename T>
SmallVectorBase class
Base class for a fast growable array.
SmallVector is a vector-like growable array that allocates its first N elements on the stack. As long as you don't need more room than that, there are no heap allocations – otherwise we spill over into the heap. This is the base class that erases the stack size template parameter for use with generic code.
Derived classes
-
template<typename T, size_class SmallVector
t N = detail::calculateDefaultSmallVectorElems<T>()> - A concrete, sized version of the SmallVectorBase<T> template.

void slang::
Resizes the array.
If larger than the current size, default constructs new elements to fill the gap. If smaller than the current size, the length is shrunk and elements are destructed.
template<typename T>
std::
Creates a constant copy of the array using the given allocator.
If the array holds pointers, const is added to the pointed-to type as well.
