| |
| </span><span class="doccomment">/// Sample a `u8`, uniformly distributed over ASCII letters and numbers: |
| /// a-z, A-Z and 0-9. |
| /// |
| /// # Example |
| /// |
| /// ``` |
| /// use rand::{Rng, thread_rng}; |
| /// use rand::distributions::Alphanumeric; |
| /// |
| /// let mut rng = thread_rng(); |
| /// let chars: String = (0..7).map(|_| rng.sample(Alphanumeric) as char).collect(); |
| /// println!("Random chars: {}", chars); |
| /// ``` |
| /// |
| /// The [`DistString`] trait provides an easier method of generating |
| /// a random `String`, and offers more efficient allocation: |
| /// ``` |
| /// use rand::distributions::{Alphanumeric, DistString}; |
| /// let string = Alphanumeric.sample_string(&mut rand::thread_rng(), 16); |
| /// println!("Random string: {}", string); |
| /// ``` |
| /// |
| /// # Passwords |
| /// |
| /// Users sometimes ask whether it is safe to use a string of random characters |
| /// as a password. In principle, all RNGs in Rand implementing `CryptoRng` are |
| /// suitable as a source of randomness for generating passwords (if they are |
| /// properly seeded), but it is more conservative to only use randomness |
| /// directly from the operating system via the `getrandom` crate, or the |
| /// corresponding bindings of a crypto library. |
| /// |
| /// When generating passwords or keys, it is important to consider the threat |
| /// model and in some cases the memorability of the password. This is out of |
| /// scope of the Rand project, and therefore we defer to the following |
| /// references: |
