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.RowTo scans single column row directly into value of type T
  2. pgx.RowToAddrOf scans single column row into pointer of type *T
  3. pgx.CollectRows with RowTo collects all single-column rows into typed slice and closes rows
  4. pgx.CollectOneRow with RowTo returns first scalar value and returns ErrNoRows when empty
  5. pgx.CollectExactlyOneRow with RowTo returns ErrTooManyRows when multiple rows are present
  6. sample helpers CollectScalarSlice, CollectScalarPointerSlice, CollectScalarOne, CollectScalarExactlyOne, and ScanSingleValue provide typed scalar scanning
