Macro uom::ISQ [−] [src]

macro_rules! ISQ {
    ($path:path, $V:ty) => { ... };
    ($path:path, $V:ty, $U:tt) => { ... };
}

Macro to implement quantity type aliases for a specific system of units and value storage type.

$path: Path to the module where the system! macro was run (e.g. ::uom::si).
$V: Underlying value storage type (e.g. f32).
$U: Optional. Base units. Pass as a tuple with the desired units: (meter, kilogram, second, ampere, kelvin, mole, candela). The system's base units will be used if no value is provided.

An example invocation is given below for a meter-kilogram-second system setup in the module mks with a system of quantities name Q. The optional units parameter to change the base units is included commented out.

mod f32 {
    Q!(mks, f32/*, (centimeter, gram, second)*/);
}
