Trait nannou_core::rand::distributions::DistString

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

    fn sample_string<R>(&self, rng: &mut R, len: usize) -> String
    where
        R: Rng + ?Sized,
    { ... }
}

String sampler

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

Required methods

fn append_string<R>(&self, rng: &mut R, string: &mut String, len: usize) where
    R: Rng + ?Sized, 

Append len random chars to string

Provided methods

fn sample_string<R>(&self, rng: &mut R, len: usize) -> String where
    R: Rng + ?Sized, 

Generate a String of len random chars

Implementors

impl DistString for Alphanumeric

impl DistString for Standard

Note: the String is potentially left with excess capacity; optionally the user may call string.shrink_to_fit() afterwards.
