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.RowToStructByNameLax scans matching columns into struct fields while leaving missing fields as zero values
  2. pgx.RowToAddrOfStructByNameLax scans matching columns into a pointer to struct
  3. pgx.RowToStructByName fails when struct fields are missing from row columns in strict mode
  4. pgx.CollectExactlyOneRow returns a single scanned struct when exactly one row is present
  5. pgx.CollectExactlyOneRow returns pgx.ErrNoRows when zero rows are returned
  6. pgx.CollectExactlyOneRow returns pgx.ErrTooManyRows when multiple rows are returned
