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

Append len random chars to string

Provided Methods

Generate a String of len random chars


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