Base usage:

trait Page{
    fn set_page(&self, p: i32){
        println!("Page Default: 1");
    }
}
trait PerPage{
    fn set_perpage(&self, num: i32){
        println!("Per Page Default: 10");
    }
}
trait Paginate: Page + PerPage{
    fn set_skip_page(&self, num: i32){
        println!("Skip Page : {:?}", num);
    }
}
impl <T: Page + PerPage>Paginate for T{}
struct MyPaginate{ page: i32 }
impl Page for MyPaginate{}
impl PerPage for MyPaginate{}
let my_paginate = MyPaginate{page: 1};
my_paginate.set_page(2);
my_paginate.set_perpage(100);
my_paginate.set_skip_page(12);
