Create the Page data structure

[gsdenys]

Description

Implement the Page data structure that contains the functions Next() and Prev(). It also stores the content of request and the page data.

During the implementation, this data structure will be discussed and a consensus must be defined

This data structure must have minimum these fields:

type Page[T any] struct {
  Elements []*T  `json:"elements"`
  Count    int64 `json:"count"`
  Page     uint  `json:"page"`
  PageSize uint  `json:"pageSize"`
  NumPages int64 `json:"totalPages"`
  HasNext  bool  `json:"hasNext"`
  HasPrev  bool  `json:"hasPrev"`
}

And the function signature are:

func (pg *Page[T]) Next() (*Page[T], error)
func (pg *Page[T]) Prev() (*Page[T], error) 

Acceptance Criteria

• 1. The Data structure must be defined and implemented
• 2. The unity test should be developed
• 3. The test coverture must be 100%
• 4. The serialization elements to json must not print the auxiliar objects like connection or repository.
