                                                                                    func ReadBloomBits

The receipt metadata fields are not guaranteed to be populated, so they should not be used. Use ReadReceipts instead if the metadata is needed.

                                                                                                                            func ReadReceipt

If it is unable to populate these metadata fields then nil is returned.

                                                                                                                                The current implementation populates these metadata fields by reading the receipts' corresponding block body, so if the block body is not found it will return nil even if the receipt itself is stored.
