Detailed Description

template<typename T, bool = (std::is_trivially_copy_constructible<T>::value) && (std::is_trivially_move_constructible<T>::value) && std::is_trivially_destructible<T>::value>
class open3d::core::SmallVectorTemplateBase< T, bool >

SmallVectorTemplateBase<TriviallyCopyable = false> - This is where we put method implementations that are designed to work with non-trivial T's.

We approximate is_trivially_copyable with trivial move/copy construction and trivial destruction. While the standard doesn't specify that you're allowed copy these types with memcpy, there is no way for the type to observe this. This catches the important case of std::pair<POD, POD>, which is not trivially assignable.
