Meta information for a query result.

• :flop - The Flop struct used in the query.
• :current_offset - The :offset value used in the query when using offset-based pagination or a derived value when using page-based pagination. Always nil when using cursor-based pagination.
• :current_page - The :page value used in the query when using page-based pagination or a derived value when using offset-based pagination. Note that the value will be rounded if the offset lies between pages. Always nil when using cursor-based pagination.
• :errors - Any validation errors that occurred. The format is the same as the result of Ecto.Changeset.traverse_errors(changeset, & &1).
• :previous_offset, :next_offset, :previous_page, :next_page - Values based on :current_page and :current_offset/page_size. Always nil when using cursor-based pagination.
• :start_cursor, :end_cursor - The cursors of the first and last record in the result set. Only set when using cursor-based pagination with :first/:after or :last/:before.
• :has_previous_page?, :has_next_page? - Set in all pagination types. Note that :has_previous_page? is always true when using cursor-based pagination with :first and :after is set; likewise, :has_next_page? is always true when using cursor-based pagination with :before and :last is set.
• :page_size - The page size or limit of the query. Set to the :first or :last parameter when using cursor-based pagination.
• :params - The original, unvalidated params that were passed. Only set if validation errors occurred.
• :total_count - The total count of records for the given query. Always nil when using cursor-based pagination.
• :total_pages - The total page count based on the total record count and the page size. Always nil when using cursor-based pagination.
