如何擁有一個具有介面輸入參數和相同類型返回值的介面的函數？

cannot use result (variable of type []entity.something) as []interface{} value in argument to utility.paginateslice compilerincompatibleassign

// paginatelist, paginates a slice based upon its page and pagesize.
func paginateslice(x []interface{}, page, pagesize int) []interface{} {
    var maxsize int = len(x)

    start := (page - 1) * pagesize
    end := start + pagesize - 1

    if start > maxsize || page < 1 || pagesize < 1 {
        start = 0
        end = 0
    } else if end > maxsize {
        end = maxsize
    }

    return x[start:end]
}

var result []entity.Something

tmps := utility.PaginateSlice(dataOfSomethingType, pagination.Page, pagination.PageSize)
for _, tmp := range tmps {
    if value, ok := tmp.(entity.Something); ok {
    result = append(result, value)
}

func PaginateSlice[S ~[]T, T any](x S, page, pageSize int) S {
    // insert body of function from question here
}
