Struct HotNbr 

Source 
pub struct HotNbr {
    pub endpoint: u32,
    pub rank: i64,
    pub edge_id: EdgeId,
}
Expand description

Hot topology half of a CSR slot: everything a traversal needs.

Packed (endpoint, rank, edge_id) without timestamp replicas. Scans that resolve visibility through the version authority (by edge_id) walk this half only, so the cold timestamp lines stay out of the cache. Assembled back into Nbr at API boundaries through Nbr::from_parts.

Rank keeps full 64-bit width: it is the caller-controlled multigraph multiplicity key, shared with endpoint key packing, WAL redo records and the query layer, so the store must hold any legal input value exactly.
