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 maps row columns to struct fields when struct has greater or equal number of fields than row columns
  2. pgx.RowToStructByNameLax respects db struct tags for column name mapping and ignores fields tagged with db:"-"
  3. pgx.RowToStructByNameLax performs case-insensitive column matching for untagged fields
  4. pgx.RowToStructByNameLax returns an error when row contains unknown column not present in struct
  5. pgx.RowToAddrOfStructByNameLax returns a pointer *T with mapped field values
  6. pgx.CollectRows with RowToStructByNameLax collects multiple rows into struct slices and closes rows upon completion
  7. pgx.CollectOneRow and pgx.CollectExactlyOneRow work with RowToStructByNameLax and return ErrNoRows and ErrTooManyRows as expected
  8. sample helpers CollectStructsLax, CollectAddrOfStructsLax, CollectOneStructLax, and CollectExactlyOneStructLax provide typed struct collection
