Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. pgx.RowToStructByPos maps row columns to struct fields positionally in declaration order
  2. pgx.RowToStructByPos ignores unexported struct fields when mapping positionally
  3. pgx.RowToAddrOfStructByPos returns a pointer to struct with positionally mapped field values
  4. pgx.CollectRows with RowToStructByPos collects multiple rows into struct slices and closes rows upon completion
  5. pgx.CollectOneRow and pgx.CollectExactlyOneRow work with RowToStructByPos and return ErrNoRows and ErrTooManyRows as expected
  6. sample helper functions provide positional struct row scanning and collection utilities
