cpf-rs

巴西 CPF 解析、验证和格式化库。

use cpf::Cpf;

// Use the `valid` function if all you need is validating a CPF number
assert!(cpf::valid("385.211.390-39"));
assert!(cpf::valid("38521139039"));
assert!(!cpf::valid("000.000.000-00"));

// Parse into a Cpf struct if you need formatting or other metadata
let cpf: Cpf = "38521139039".parse()?;
assert_eq!(format!("{cpf}"), "385.211.390-39");
assert_eq!(cpf.as_str(), "38521139039");
assert_eq!(cpf.digits(), [3, 8, 5, 2, 1, 1, 3, 9, 0, 3, 9]);

// Note that the Cpf struct is guaranteed to always be valid
assert!("000.000.000-00".parse::<Cpf>().is_err());
assert!(cpf::valid("385.211.390-39".parse::<Cpf>()?));

支持 no_std

该库不进行动态分配，可以通过禁用 std 标志在 no_std 环境中使用

[dependencies]
cpf = { version = "0.3", default-features = false }

支持随机 CPF 生成

启用 rand 功能标志以启用随机 CPF 生成

[dependencies]
cpf = { version = "0.3", features = ["rand"] }
rand = "0.8"

use cpf::Cpf;
use rand;
use rand::Rng;

let cpf = rand::thread_rng().gen::<Cpf>();
