template<typename T>
slang::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.
