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.CollectRows iterates through rows and collects primitive types using pgx.RowTo
  2. pgx.CollectRows maps column fields into struct using pgx.RowToStructByName
  3. pgx.CollectRows maps pointer to struct using pgx.RowToAddrOfStructByName
  4. pgx.CollectRows handles subset columns with pgx.RowToStructByNameLax
  5. pgx.CollectRows scans column key-value pairs into map using pgx.RowToMap
  6. pgx.CollectOneRow extracts a single row and returns pgx.ErrNoRows when result is empty
  7. pgx.CollectExactlyOneRow returns pgx.ErrTooManyRows when query yields more than one row
  8. pgx.CollectRows closes rows automatically on completion and returns empty slice for zero rows
