Expand description
Row-level feature source for the typed scoring contract.
Structs§
- Accounted
Host Scores - Engine-owned callback scores whose allocation remains charged until drop. The borrower cannot detach the score buffer from its query reservation.
- Binding
Score Features - Reads scoring features from one row.
- Host
Scorer Batch - Borrowed inputs for the host-scoring escape hatch. Scratch allocations must reserve this query account before allocation and release their leases before returning; feature rows cannot escape the call.
- Host
Scorer Descriptor - Validated identity and logical per-row cost for a host’s batch scorer. Query attachments include name/version in their cache identity. This cost is a planning hint, not elapsed time.
Traits§
- Host
Scorer - Batch scorer contract for a concrete formula that templates cannot express.
Functions§
- execute_
host_ scorer - Executes one complete, explicitly bounded cohort supplied by the engine.
- reference_
time_ millis - Wall clock the specification ages timestamp features against, in epoch milliseconds.
