cuda::experimental::mr::basic_any_resource

Defined in include/cuda/experimental/__memory_resource/any_resource.cuh

template<cuda::mr::_AllocType _Alloc_type, class ..._Properties> class basic_any_resource : public cuda::mr::_Resource_base<_Alloc_type, cuda::mr::_WrapperType::_Owning>, private cuda::mr::_Filtered_vtable<_Properties...>

Base class for a type erased owning wrapper around a memory resource

basic_any_resource abstracts the differences between a resource and an async resource away, allowing efficient interoperability between the two.

Public Functions

template<class _Resource, class __resource_t = cuda::std::remove_cvref_t<_Resource>> inline basic_any_resource(_Resource &&__res) noexcept

Constructs a basic_any_resource from a type that satisfies the resource or async_resource concept as well as all properties.

Parameters: __res – The resource to be wrapped within the basic_any_resource.

template<class _Resource, class ..._Args> inline basic_any_resource(cuda::std::in_place_type_t<_Resource>, _Args&&... __args) noexcept

Constructs a basic_any_resource wrapping an object of type _Resource that is constructed from __args… . _Resource must satisfy the resource or async_resource concept, and it must provide all properties in _Properties… .

Parameters: __args – The arguments used to construct the instance of _Resource to be wrapped within the basic_any_resource.

template<cuda::mr::_AllocType _OtherAllocType, class ..._OtherProperties> inline basic_any_resource(basic_any_resource<_OtherAllocType, _OtherProperties...> __other) noexcept

Conversion from a basic_any_resource with the same set of properties but in a different order. This constructor also handles conversion from any_async_resource to any_resource.

Parameters: __other – The other basic_any_resource.

inline basic_any_resource(basic_any_resource &&__other) noexcept

Move-constructs a basic_any_resource from another one, taking ownership of the stored resource.

Parameters: __other – The other basic_any_resource.

inline basic_any_resource &operator=(basic_any_resource &&__other) noexcept

Move-assigns another basic_any_resource, taking ownership of the stored resource.

Parameters: __other – The other basic_any_resource.

inline basic_any_resource(const basic_any_resource &__other)

Copy-constructs a basic_any_resource from another one.

Parameters: __other – The other basic_any_resource.

inline basic_any_resource &operator=(const basic_any_resource &__other)

Copy-assigns another basic_any_resource.

Parameters: __other – The other basic_any_resource.

inline ~basic_any_resource() noexcept: Destroys the stored resource.

inline void swap(basic_any_resource &__other) noexcept

Swaps a basic_any_resource with another one.

Parameters: __other – The other basic_any_resource.

template<class ..._OtherProperties, ::cuda::std::enable_if_t<(sizeof...(_Properties) == sizeof...(_OtherProperties)) && __properties_match<_OtherProperties...>, int> = 0> inline bool operator==(const basic_any_resource<_Alloc_type, _OtherProperties...> &__rhs) const

Equality comparison between two basic_any_resource.

Parameters: __rhs – The other basic_any_resource
Returns: Checks whether both resources have the same equality function stored in their vtable and if so returns the result of that equality comparison. Otherwise returns false.

template<class ..._OtherProperties, ::cuda::std::enable_if_t<(sizeof...(_Properties) == sizeof...(_OtherProperties)) && __properties_match<_OtherProperties...>, int> = 0> inline bool operator!=(const basic_any_resource<_Alloc_type, _OtherProperties...> &__rhs) const

Inequality comparison between two basic_any_resource.

Parameters: __rhs – The other basic_any_resource
Returns: Checks whether both resources have the same equality function stored in their vtable and if so returns the inverse result of that equality comparison. Otherwise returns true.

template<class _Property, ::cuda::std::enable_if_t<property_with_value<_Property>&&(cuda::std::__is_included_in_v<_Property, _Properties...>), int> = 0> inline __property_value_t<_Property> get_property(const basic_any_resource &__res, _Property) noexcept: Forwards the stateful properties.

Friends

template<class _Property, ::cuda::std::enable_if_t<(!property_with_value<_Property>) && (cuda::std::__is_included_in_v<_Property, _Properties...>), int> = 0> inline friend void get_property(const basic_any_resource&, _Property) noexcept: Forwards the stateless properties.
