      "description": "Reads the fields of a GTIN: structure, length, GS1 prefix, whether the prefix is Brazilian or a restricted range, and the check digit. Accepts the same input as `gtin.isValid` without options and returns `null` exactly when `gtin.isValid` is `false`.\n\n- `type` (`GTIN-8`, `GTIN-12`, `GTIN-13` or `GTIN-14`) and `length` describe the value as written. A GTIN-14 that starts with 0 is reported as `GTIN-14`.\n- `prefix` is read from the 14-digit form (the value left-padded with zeros): positions 7 to 9 when positions 2 to 6 are zeros (a GS1-8 prefix, as in every GTIN-8), positions 2 to 4 otherwise. The first digit, a padding zero or the indicator digit, is never part of the prefix. So `10000078912349` has prefix `789`, the prefix of a GTIN-12 starts with 0, and a GTIN-14 has the prefix of the GTIN it packs.\n- `isBrazilian` is `true` for the prefixes 789 and 790 (GS1 Brasil, as the SEFAZ rules name them).\n- `isRestrictedCirculation` is `true` for the Restricted Circulation Number ranges of the GS1 General Specifications: GS1 prefixes 02, 04, 20 to 29 and 0000000, and GS1-8 prefixes 000 to 099 and 200 to 299. A restricted range does not make the code invalid. It is only reported.\n- `checkDigit` is the last digit, as a number.\n- The prefix is not checked against the list of GS1 Member Organisations, and no country name is returned. The prefix names the GS1 organisation that licensed the number, not the country of origin.\n- Returns a new object on every call.",

The check digit brings the sum to the next multiple of 10. This is what NF-e rules I03-10 and I12-10 check in the `cEAN` and `cEANTrib` fields.\n- Only a string of digits is read; whitespace around the value is ignored. A mask, a space inside the value and a letter are rejected. A number is also rejected, because the leading zeros define the length.\n- A value of zeros only is rejected at any length, although its check digit is valid. This is a rule of the library, not of the NF-e or GS1: rejection 611 is only the check digit, and GS1 reserves the prefix `0000000` for Restricted Circulation Numbers within a company instead of forbidding it. Zeros are rejected as the usual placeholder for a missing GTIN.\n- `SEM GTIN`, the text the NF-e uses for a product without a GTIN, is rejected.\n- `options.lengths` limits the accepted lengths, for example `{ lengths: [13] }`. An empty list accepts nothing. When it is missing or is not a list, the four lengths are accepted.\n- The prefix does not change the result: Restricted Circulation Numbers and the ISBN, ISSN and coupon ranges share the structure and are valid. Use `gtin.getInfo` to read the prefix.\n- The prefix is not checked against a list. SEFAZ also checks it against its own \"Tabela Prefixo GS1\" (rules I03-20 and I12-20), which the library does not carry. Registration with GS1 (the Cadastro Centralizado de GTIN) cannot be checked offline.",
