Detailed Description

template<typename T>
class wpi::SmallVectorTemplateBase< T, true >

SmallVectorTemplateBase<TriviallyCopyable = true> - This is where we put method implementations that are designed to work with trivially copyable T's.

This allows using memcpy in place of copy/move construction and skipping destruction.

◆ TakesParamByValue

template<typename T >
constexpr bool wpi::SmallVectorTemplateBase< T, true >::TakesParamByValue = sizeof(T) <= 2 * sizeof(void *)
