Classes
struct	Stroika::Foundation::Memory::SharedByValueSupport::DefaultValueCopier_FunctionObject< T, SHARED_IMPL >
	DefaultValueCopier_FunctionObject same as DefaultValueCopier, but as a function object. More...
struct	Stroika::Foundation::Memory::SharedByValueSupport::ExplicitTraits< T, SHARED_IMPL, DEFAULT_COPIER_TYPE, DEFAULT_COPIER, INSTANCE_COPIER_TYPE >
	ExplicitTraits is a utility struct to provide parameterized TRAITS support for SharedByValue<> More...
class	Stroika::Foundation::Memory::SharedByValue< T, TRAITS >
	SharedByValue is a utility class to implement Copy-On-Write (aka COW) - sort of halfway between unique_ptr and shared_ptr. More...

Typedefs
using	Stroika::Foundation::Memory::SharedByValueSupport::MissingCopierTypeSentinel = nullptr_t
template<typename T , auto COPIER_INSTANCE = &DefaultValueCopier<T, shared_ptr<T>>>
using	Stroika::Foundation::Memory::SharedByValueSupport::DefaultTraits_NoInstanceCopier = ExplicitTraits< T, shared_ptr< T >, decltype(COPIER_INSTANCE), COPIER_INSTANCE, MissingCopierTypeSentinel >
	Unified DefaultTraits_NoInstanceCopier - works with both function objects and function pointers.
template<typename T , typename COPIER_TYPE = function<shared_ptr<T> (const T&)>>
using	Stroika::Foundation::Memory::SharedByValueSupport::DefaultTraits_InstanceCopierOnly = ExplicitTraits< T, invoke_result_t< COPIER_TYPE, T >, MissingCopierTypeSentinel, MissingCopierTypeSentinel{}, COPIER_TYPE >
	SharedByValue traits object for per-instance constructor specification of shared_ptr copier only.
template<typename T , typename DEFAULT_COPIER_TYPE = DefaultValueCopier_FunctionObject<T, shared_ptr<T>>, typename INSTANCE_COPIER_TYPE = function<shared_ptr<T> (const T&)>>
using	Stroika::Foundation::Memory::SharedByValueSupport::DefaultTraits_DefaultAndInstanceCopiers = ExplicitTraits< T, invoke_result_t< INSTANCE_COPIER_TYPE, T >, DEFAULT_COPIER_TYPE, DEFAULT_COPIER_TYPE{}, INSTANCE_COPIER_TYPE >
	Both a default copier, and a function<sharedimp(T)> instance copier.
template<typename T , auto COPIER_INSTANCE = &DefaultValueCopier<T, shared_ptr<T>>>
using	Stroika::Foundation::Memory::SharedByValueSupport::DefaultTraits = DefaultTraits_NoInstanceCopier< T, COPIER_INSTANCE >
	DefaultTraits is a utility struct to provide parameterized support for SharedByValue<>

Functions
template<typename T , typename SHARED_IMPL = shared_ptr<T>>
SHARED_IMPL	Stroika::Foundation::Memory::SharedByValueSupport::DefaultValueCopier (const T &t)
	DefaultValueCopier is the default value-copier for copying SharedByValue (thing that clones a shared_ptr)
