Trait rand::distributions::DistString[−][src]

pub trait DistString {
    fn append_string<R: Rng + ?Sized>(
        &self, 
        rng: &mut R, 
        string: &mut String, 
        len: usize

String sampler

Sampling a String of random characters is not quite the same as collecting a sequence of chars. This trait contains some helpers.
