Detailed Description

template<class T, class AttachResultType = typename detail::safe_get_attach_result<T, span<byte>>::type>
struct kvstore_v1_xxx::traits::is_attachable< T, AttachResultType >

True if a type is trivially attachable, or has defined an ADL discovered free function of the form span<byte> in_place_attach<T>(span<byte>).

The most common custom object attachment action is to initialise all pointers and references with something valid for the running C++ program. When in_place_attach<T> is called, the lifetime of T has not yet begun, so any vptr etc. will be invalid.
