Detailed Description

template<typename index_T = index>
class DNDS::AdjacencyRow< index_T >

Non-owning span (pointer, size) into an ArrayAdjacency row.

Serves as the return value of ArrayAdjacency::operator[]. It is the "typed row handle" equivalent of std::span<index_T> with a few DNDSR-specific conveniences:

• indexing is bounds-checked in debug (DNDS_assert);
• assignment from / conversion to std::vector<index>;
• device-callable accessors so kernels can walk adjacency rows.

The span does not own the underlying storage; it must not outlive the backing ArrayAdjacency.

Template Parameters

index_T

Either DNDS::index (mutable) or const DNDS::index.
