HyperUtility

Data structure

Simple implementation of Stack and Queue data structure. Both structure were backend with array of []interface{}

Stack

Implement the Stack data structure FILO (First In Last Out). In stack, the first data added into the stack can only be retrieved the latest, and the last added data into the stack can be retrieved immediately.

+---+---+---+---+  <--- push
| 1 | 2 | 3 | n |
+---+---+---+---+  ---> pop

Queue

Implement the Queue data structure FIFO (First In First Out). In Queue, the first data added into the Queue can be retrieved immediately, and the last added data into the stack can be retrieved the latest.

           +---+---+---+---+
pop <---   | 1 | 2 | 3 | n |  <--- push
           +---+---+---+---+

io.Writer

MultipleWriter

MultipleWriter easily write byte stream into multiple write stream. Its very useful for the case like writing multiple log, for example, one to the console os.StdErr and one to some external file writer.

                       +--> writer_a.Write()
                       |
multiWriter.Write() ---+
                       |
                       +--> writer_b.Write()
