Struct Per 

pub struct Per<N, D>(/* private fields */)
where
    N: Unit,
    D: Unit;

Unit representing the division of two other units.

Per<N, D> corresponds to N / D and carries both the dimensional information and the scaling ratio between the constituent units. It is generic over any numerator and denominator units, which allows implementing arithmetic generically for all pairs without bespoke macros.

Trait Implementations

impl<N, D> Clone for Per<N, D>

where N: Clone + Unit, D: Clone + Unit,

fn clone(&self) -> Per<N, D>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<N, D> Debug for Per<N, D>

where N: Debug + Unit, D: Debug + Unit,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<N, D> PartialEq for Per<N, D>

where N: PartialEq + Unit, D: PartialEq + Unit,

fn eq(&self, other: &Per<N, D>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<N, D> PartialOrd for Per<N, D>

where N: PartialOrd + Unit, D: PartialOrd + Unit,

fn partial_cmp(&self, other: &Per<N, D>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<N, D> Unit for Per<N, D>

where N: Unit, D: Unit, <N as Unit>::Dim: DimDiv<<D as Unit>::Dim>, <<N as Unit>::Dim as DimDiv<<D as Unit>::Dim>>::Output: Dimension,

const RATIO: f64

Unit-to-canonical conversion factor.

const SYMBOL: &'static str = ""

Printable symbol, shown by core::fmt::Display.

type Dim = <<N as Unit>::Dim as DimDiv<<D as Unit>::Dim>>::Output

Dimension to which this unit belongs.

impl<N, D> UnitDiv<Per<N, D>> for N
