CPF

Brazilian CPF parsing, validating and formatting library.

use cpf::CPF;

// If all you need is validating a CPF number, use the `valid` function:
assert!(cpf::valid("38521139039"));

// For formatting and additional metadata from the number, parse into the CPF struct:
let cpf: CPF = "38521139039".parse().unwrap();

assert_eq!(cpf.formatted().as_str(), "385.211.390-39");
assert_eq!(cpf.digits(), &[3, 8, 5, 2, 1, 1, 3, 9, 0, 3, 9]);

no_std support

The library can be used on no_std environments by disabling the std flag:

[dependencies]
cpf = { version = "0.1", default-features = false }

Random CPF generation support

The rand feature flag enables random CPF generation:

[dependencies]
cpf = { version = "0.1", features = ["rand"] }
rand = "0.8"

use cpf::CPF;
use rand;
use rand::Rng;

let cpf: CPF = rand::thread_rng().gen();
