Struct VecVertexCursor 

Source 
pub struct VecVertexCursor { /* private fields */ }
Expand description

Vertex cursor backed by a pre-materialized Vec<Vertex>.

This is the default implementation used when the storage backend does not yet provide a native lazy cursor. It is semantically identical to calling [StorageReader::scan_vertices] upfront.
