Detailed Description

template<typename T>
class DNDS::host_device_vector_r1< T >

Host + optional device vector of trivially copyable T.

Primary storage type used inside Array. Always maintains a host copy; on demand, a device mirror can be created via to_device. Many "vector-like" std::vector operations (resize, assign, operator[]) have been reimplemented so the class can be used as a drop-in replacement in DNDSR code paths that need device-awareness.

Use the variant host_device_vector (a thin alias below) to pick up the appropriate specialisation based on element type.
