Detailed Description

template<class TView, DeviceBackend B>
struct DNDS::deviceViewVector< TView, B >

Contiguous host_device_vector of non-owning views, mirrored on a device.

Many CUDA kernels need "a vector of array views" – e.g., the per-cell adjacency views for a mesh, bundled into one flat array on the GPU. This helper takes a factory callback that produces the i-th view, stores all views in a host_device_vector, and pushes the result to the chosen backend in one call.

Template Parameters

TView	View type to store (must be trivially copyable).
B	Target device backend.
