# [−][src]Struct rand::distributions::Alphanumeric

    pub struct Alphanumeric;

Sample a `char`, uniformly distributed over ASCII letters and numbers: a-z, A-Z and 0-9.

# Example

    use std::iter;
    use rand::{Rng, thread_rng};
    use rand::distributions::Alphanumeric;

    let mut rng = thread_rng();
    let chars: String = iter::repeat(())
            .map(|()| rng.sample(Alphanumeric))
            .take(7)
            .collect();
    println!("Random chars: {}", chars);

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
