Crate scalc

A type that ensures calculation safety and prevents itself from overflow

Get started

use scalc::SCell;
 
fn main() {
   let a = SCell::<i32>::new(12) * SCell::<i32>::new(3);
   assert_eq!(*a.get_data(), 36);
 
   // `error_tag` will be `true` in the presence of overflow behavior(s)
   let a = SCell::<i32>::new(std::i32::MAX) + SCell::<i32>::new(1);
   assert_eq!(a.is_overflowed(), true);
   assert_eq!(*a.get_data(), 1);
}

You can also use New Type Idiom in combination of derive_more to have better experience.
