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.ForEachRow iterates through rows and invokes callback function
  2. pgx.ForEachRow scans values into destination slice for each row
  3. pgx.ForEachRow returns CommandTag with rows affected count upon completion
  4. pgx.ForEachRow automatically closes rows upon completion or error
  5. pgx.ForEachRow returns 0 rows affected and nil error for empty rows
  6. pgx.ForEachRow stops iteration and propagates callback error
  7. pgx.ForEachRow propagates scan errors when destination slice is invalid
  8. sample helper functions process rows, collect values, and count matching rows using pgx.ForEachRow
