Data_Namespace::detail::TypedThrustAllocatorState Class Reference

Manages the underlying state of a TypedThrustAllocator. The state consists of: DataMgrMemoryResource: this instance holds onto a pointer of the ThrustAllocator which performs generic allocations thrust::device_ptr_memory_resource: this instance is an adapter that converts the pointer returned from the DataMgrMemoryResource to a thrust::device_ptr.

Detailed Description

Manages the underlying state of a TypedThrustAllocator. The state consists of: DataMgrMemoryResource: this instance holds onto a pointer of the ThrustAllocator which performs generic allocations thrust::device_ptr_memory_resource: this instance is an adapter that converts the pointer returned from the DataMgrMemoryResource to a thrust::device_ptr.
