class Random extends AnyRef

The Random class provides methods to generate pseudo-random numbers via a plug-in PRNG, which is simply any function that generates a Long primitive.
case class RandomStream(rng: () ⇒ Long) extends InputStream with Product with Serializable

Create a random InputStream of bytes from a PRNG.

object Concat extends LowPriorityConcatImplicits

Provides a way to append two arrays of possibly different types together by intelligently promoting primitive types where possible.

def buildStr(count: Int, total: Int, callback: (Int) ⇒ String, break: ⇒ String = " ... "): String

Creates a string out of count number of elements extracted from total elements between offsets [0 .
Creates a string out of count number of elements extracted from total elements between offsets [0 ... count / 2) and (total - count / 2 ... total), using a callback that generates a string at each offset, and inserting a break string if count > total.
count
Number of elements to print
total
Total number of elements in sequence
callback
Generates a string at each offset
