Struct Unitless 

pub struct Unitless;

Zero-sized marker type for dimensionless quantities.

Unitless represents a dimensionless unit with a conversion ratio of 1.0 and an empty symbol. It is used to model the result of simplifying same-unit ratios (e.g., Meters / Meters) into a plain “number-like” Quantity<Unitless>.

Unlike a type alias to f64, this is a proper zero-sized type, which ensures that only explicitly constructed Quantity<Unitless> values are treated as dimensionless, not bare f64 primitives.

Trait Implementations

impl Clone for Unitless

fn clone(&self) -> Unitless

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Unitless

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

Formats the value using the given formatter.

impl PartialEq for Unitless

fn eq(&self, other: &Unitless) -> 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 PartialOrd for Unitless

fn partial_cmp(&self, other: &Unitless) -> 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 Unit for Unitless

const RATIO: f64 = 1f64

Unit-to-canonical conversion factor.

const SYMBOL: &'static str = ""

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

type Dim = Dimensionless

Dimension to which this unit belongs.

impl Copy for Unitless
