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. assert pgx.CollectRows iterates through rows using RowToFunc to produce a strongly typed slice
  2. assert pgx.RowToMap maps database column names from field descriptions to scanned values in a map
  3. assert pgx.RowToStructByPos scans columns into struct fields matched by positional index
  4. assert pgx.RowToAddrOfStructByPos scans row columns positionally and returns a pointer to struct
  5. assert pgx.CollectOneRow returns the first row value and yields ErrNoRows for empty result sets
  6. assert pgx.CollectExactlyOneRow yields ErrTooManyRows when the result set contains more than one row
  7. assert pgx.ForEachRow iterates over rows scanning into positional targets and returns CommandTag
  8. assert pgx.RowTo scans single-column values directly into basic Go types
