Detailed Description

template<typename T, std::size_t InlineCapacity>
union real::detail::small_vec< T, InlineCapacity >::Storage

The either-or storage: the inline buffer, or a pointer to the heap block once the vector has spilled. is_heap_ says which member is active.

Constructor & Destructor Documentation

template<typename T , std::size_t InlineCapacity>

constexpr real::detail::small_vec< T, InlineCapacity >::Storage::Storage ( )

inlineconstexprnoexcept

Starts in the inline state.

Run time leaves the inline buffer uninitialized (see the class warning). Constant evaluation activates the whole inline_block (a constexpr union can activate a class-type member, not a bare C array); adopt_heap and revert_to_inline switch the active member.
