Type Alias Resistivity 

pub type Resistivity = Qty<3, 1, -3, -2, 0, 0, 0>;

Ω·m — resistance times length. The property of a material, where Resistance is the property of a particular piece of one.

The distinction is the whole point of a field formulation of current: R = ρL/A is a statement about a uniform bar, and a shape that is not a uniform bar does not have one.

Aliased Type

pub struct Resistivity(/* private fields */);

Implementations

impl Resistivity

pub fn ohm_m(v: f64) -> Resistivity

Ohm-metres. Copper is 1.724e-8 at 20 °C, aluminium 2.65e-8, and a resistor’s ceramic substrate is fourteen orders of magnitude up from either.

pub fn micro_ohm_cm(v: f64) -> Resistivity

µΩ·cm, which is what a materials datasheet quotes: copper is 1.724.

pub fn conductivity(self) -> Conductivity

The conductivity that is its reciprocal. Zero resistivity gives an infinite conductivity, which is the honest answer and not a panic.
