Struct brids::Cnpj

pub struct Cnpj(_);

A valid CNPJ number. Parsing recognizes numbers with or without separators (dot, minus, slash, and space).

Implementations

impl Cnpj

pub fn from_slice(slice: &[u8]) -> Result<Self, ParseCnpjError>

Parses a byte slice of numbers as an CNPJ, guessing the missing parts.

Examples

Basic usage:

use brids::Cnpj;

match Cnpj::from_slice(&[1, 2, 3, 4, 5, 6, 7, 8, 0, 0, 0, 1, 9, 5]) {
    Ok(cnpj) => println!("{} is a valid number.", cnpj),
    Err(err) => println!("Error: {}", err),
}

Guess the check digits:

use brids::Cnpj;

match Cnpj::from_slice(&[1, 2, 3, 4, 5, 6, 7, 8, 0, 0, 2, 7]) {
    Ok(cnpj) => println!("{} is a valid number.", cnpj),
    Err(err) => println!("Error: {}", err),
}

Guess the branch and check digits:

use brids::Cnpj;

match Cnpj::from_slice(&[1, 2, 3, 4, 5, 6, 7, 8]) {
    Ok(cnpj) => println!("{} is a valid number.", cnpj),
    Err(err) => println!("Error: {}", err),
}

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

Returns a byte slice of the numbers.

Examples

use brids::Cnpj;

let cnpj = Cnpj::generate();
let bytes = cnpj.as_bytes();

pub fn branch(&self) -> u16

Returns the entity branch.

Examples

use brids::Cnpj;

let cnpj = Cnpj::generate();
let branch = cnpj.branch();

pub fn generate() -> Self

Generates a random number, using rand::thread_rng (optional dependency enabled by default). To use a different generator, instantiate the generator directly.

Examples

use brids::Cnpj;

let cnpj = Cnpj::generate();

impl Distribution<Cnpj> for Standard

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> Cnpj

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R, 'a>(&'a self, rng: &'a mut R) -> DistIter<'a, Self, R, T>where
    Self: Sized,
    R: Rng,

Create an iterator that generates random values of T, using rng as the source of randomness.

impl FromStr for Cnpj

type Err = ParseCnpjError

The associated error which can be returned from parsing.

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Cnpj

fn cmp(&self, other: &Cnpj) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,
