Expand description

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

source

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

Append len random chars to string

-

Provided Methods

source

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

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.
