Struct cnpj::Cnpj

pub struct Cnpj { /* fields omitted */ }

A valid CNPJ number.

Initialize a Cnpj from a &str or an array of digits:

use cnpj::Cnpj;

let cnpj1 = "96.769.900/0001-77".parse::<Cnpj>()?;
let cnpj2 = Cnpj::try_from([9, 6, 7, 6, 9, 9, 0, 0, 0, 0, 0, 1, 7, 7])?;
assert_eq!(cnpj1, cnpj2);

Note that the Cnpj struct can only be initialized after a successfully parse, so it is guaranteed to always be valid.

use cnpj::Cnpj;

let cnpj = "00.000.000/0000-00".parse::<Cnpj>();
assert!(cnpj.is_err());

Implementations

impl Cnpj

pub fn digits(&self) -> &[u8; 14]

The Cnpj digits.

use cnpj::Cnpj;

let cnpj: Cnpj = "96.769.900/0001-77".parse()?;
assert_eq!(cnpj.digits(), &[9, 6, 7, 6, 9, 9, 0, 0, 0, 0, 0, 1, 7, 7]);

pub fn formatted(&self) -> ArrayString<18>

Formats a Cnpj number.

use cnpj::Cnpj;

let cnpj: Cnpj = "96769900000177".parse()?;
assert_eq!(cnpj.formatted().as_str(), "96.769.900/0001-77");

Note that numbers with less than 14 digits will be padded by zeros.

use cnpj::Cnpj;

let cnpj: Cnpj = "1.219.900/0001-97".parse()?;
assert_eq!(cnpj.formatted().as_str(), "01.219.900/0001-97");
