This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. MemoryRows implements the pgx.Rows interface providing FieldDescriptions, Next, Scan, Values, RawValues, CommandTag, Err, Close, and Conn
  2. pgx.Rows Next and Scan iterate and decode positional column values into Go typed destination pointers
  3. pgx.Rows Values and RawValues return decoded any slices and raw byte slices for the active row
  4. pgx.Rows Scan supports nil destinations to skip column decoding without error
  5. pgx.Rows Scan returns ScanArgError with column index and field name when destination type is incompatible
  6. pgx.CollectRows, pgx.CollectOneRow, and pgx.ForEachRow process pgx.Rows result sets offline
  7. pgx.RowToMap and pgx.RowToStructByName map active row values into map and struct instances via pgx.Rows and pgx.RowScanner
  8. pgx.Rows Close is idempotent and Err preserves errors after closure
