Crate simple-si-units-core exports the following:

NumLike

This is an ergonomic trait bundle that combines the following:

• std::ops::Add
• std::ops::AddAssign
• std::ops::Sub
• std::ops::SubAssign
• std::ops::Mul
• std::ops::MulAssign
• std::ops::Div
• std::ops::DivAssign
• std::ops::Neg
• Clone
• std::fmt::Debug
• std::fmt::Display

Thus you can use this trait as part of a struct or function template definition, like this:

use simple_si_units_core::NumLike;
pub struct MyUnit<DT: NumLike> {
    v: DT,
}

impl<DT: NumLike> std::ops::Add<Self> for MyUnit<DT> {
    type Output = Self;
    fn add(self, rhs: Self) -> Self::Output {
        return Self { v: self.v + rhs.v };
    }
}

impl<DT: NumLike> std::ops::Sub<Self> for MyUnit<DT> {
    type Output = Self;
    fn sub(self, rhs: Self) -> Self::Output {
        return Self { v: self.v - rhs.v };
    }
}
