Crate simple-si-units-macros exports the following derive macros:
Unit
This macro uses the NumLike
trait from simple-si-units-core to derive all of the relevant mathematical operators for the derived struct, so long as that struct contains only a single named field. For example:
use simple_si_units_macros::UnitStruct;
use simple_si_units_core::NumLike;
#[derive(UnitStruct, Debug, Clone)]
struct HyperVelocity<T: NumLike>{
square_meters_per_second: T
}
fn weighted_hypervel_sum<T: NumLike>(a: HyperVelocity<T>, b: HyperVelocity<T>, weight: f64) -> HyperVelocity<T>
where T:NumLike + From<f64>
{
return weight*a + (1.-weight)*b;
}
