public class FastStr
extends StrBase<FastStr>
implements RandomAccess, CharSequence, Serializable, Comparable<FastStr>
```
FastStr implements the same contract of Str with the a char array. This class is marked as Fast because of the following points: 1. When unsafeOf(String) is called, it share the internal value (the char array) of the String been passed in 2. when unsafeOf(char[]) is called, it use the char array passed in directly without copy operation 3. subList and substring works at O(1) because it will NOT copy the internal char array Note, this class shall be used with caution as it might prevent a very large char array from been garbage collected when the char array is passed to a FastStr or substr of the fast string
