Trait Accu 

pub trait Accu<A> {
    // Required methods
    fn up(self) -> A;
    fn down(a: A) -> Self;
}

Conversion trait between base and accumulator type

Required Methods

fn up(self) -> A

Cast up to accumulator type

This is a primitive cast.

assert_eq!(3i32.up(), 3i64);

fn down(a: A) -> Self

Cast down from accumulator type

This is a primitive cast.

assert_eq!(i16::down(3i32), 3i16);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
