👍 Space and time complexity?
I like the use of the hash here!
| @store[@front] = element | ||
| return element | ||
| elsif @front == (@rear + 1) % @size # queue full | ||
| puts("the qeue is full yo") |
| return element | ||
| elsif @front == (@rear + 1) % @size # queue full | ||
| puts("the qeue is full yo") | ||

I suggest you raise a different error here.
| @rear = -1 | ||
| end | ||
|
|
||
| def enqueue(element) |
| qeue_front = self.front | ||
| if @front != @rear | ||
| @store[@front] = nil | ||
| @front += 1 |

Suggested change
| @front += 1 | |
| @front = (@front + 1) % @store.length |

You should probably check to see if the Queue is empty
| return @store[@front] | ||
| end | ||
|

Why not use the positions of front and rear to calculate the size of the Queue.
| return count | ||
| end | ||
|
|

| def empty? |

Again I suggest that you use front and rear to tell if the queue is empty.
