cpf-rs

Brazilian CPF parsing, validating and formatting library.

```rust 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()?; asserteq!(format!("{}", cpf), "385.211.390-39"); asserteq!(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!("38521139030".parse::().is_err()); assert!(cpf::valid("385.211.390-39".parse::()?)); ```

no_std support

The library makes no dinamic allocation and can be used on no_std environments by disabling the std flag:

toml [dependencies] cpf = { version = "0.2", default-features = false }

Random CPF generation support

The rand feature flag enables random CPF generation:

toml [dependencies] cpf = { version = "0.2", features = ["rand"] } rand = "0.8"

```rust use cpf::Cpf; use rand; use rand::Rng;

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