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.ScanRow decodes raw row data into destination variables in text format
  2. pgx.ScanRow decodes raw row data into destination variables in binary format
  3. pgx.ScanRow skips decoding columns when destination pointer is nil
  4. pgx.ScanRow returns pgx.ScanArgError with column index and field name when scanning fails
  5. pgx.ScanArgError implements Unwrap returning underlying error
  6. pgx.ScanRow returns error when fieldDescriptions and values length differ
  7. pgx.ScanRow returns error when fieldDescriptions and destinations length differ
  8. sample helpers provide typed row decoding and scan error inspection utilities
