cpf-rs

Brazilian CPF parsing, validating and formatting library.

```rust 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 a Cpf struct: let cpf: Cpf = "38521139039".parse().unwrap();

asserteq!(cpf.formatted().asstr(), "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:

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

Random CPF generation support

The rand feature flag enables random CPF generation:

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

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

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