Class thrust::mr::stateless_resource_allocator

A helper allocator class that uses global instances of a given upstream memory resource. Requires the memory resource to be default constructible.

Template Parameters:

• T the type that will be allocated by this allocator.
• Upstream the upstream memory resource to use for memory allocation. Must derive from thrust::mr::memory_resource and must be final (in C++11 and beyond).

Inherits From:

• thrust::mr::allocator< T, Upstream >
• thrust::mr::validator< MR >

Member Functions

Function thrust::mr::stateless_resource_allocator::stateless_resource_allocator

_CCCL_EXEC_CHECK_DISABLE _CCCL_HOST_DEVICE stateless_resource_allocator(); Default constructor. Uses get_global_resource to get the global instance of Upstream and initializes the allocator base subobject with that resource.

Function thrust::mr::stateless_resource_allocator::stateless_resource_allocator

_CCCL_HOST_DEVICE stateless_resource_allocator(const stateless_resource_allocator & other); Copy constructor. Copies the memory resource pointer.

Function thrust::mr::stateless_resource_allocator::stateless_resource_allocator

template <typename U> _CCCL_HOST_DEVICE stateless_resource_allocator(const stateless_resource_allocator< U, Upstream > & other); Conversion constructor from an allocator of a different type. Copies the memory resource pointer.

Function thrust::mr::stateless_resource_allocator::operator=

stateless_resource_allocator & operator=(const stateless_resource_allocator &) = default;

Function thrust::mr::stateless_resource_allocator::~stateless_resource_allocator

_CCCL_HOST_DEVICE ~stateless_resource_allocator(); Destructor.
