That would be great. Yeah, the only way I could see it is creating the trait and implementing it for all primitives.

You can see an example of this in Recip

dimensioned/src/traits.rs

Lines 156 to 166 in a946893

 pub trait Recip { 

 /// The resulting type after taking the reciprocal 

 type Output; 

 /// The method for taking the reciprocal 

 fn recip(self) -> Self::Output; 

 } 

 impl_unary!(f32, Recip, recip); 

 impl_unary!(f64, Recip, recip);

Abs probably doesn't need the associated type Output. That is, unless we want to support types that change under absolute value. I can't think of what those would be outside of typenum, unless we wanted to do something like have i32::abs() return a u32, but that is probably not useful.
