Enum Quantities 

pub enum Quantities {
    AmountOfSubstance(AmountOfSubstance),
    Angle(Angle),
    Dimensionless(Dimensionless),
    ElectricCurrent(ElectricCurrent),
    Length(Length),
    Luminance(Luminance),
    Mass(Mass),
    TemperatureInterval(TemperatureInterval),
    Time(Time),
}

A wrapper to hold all quantities supported by this library. It is analogous to Units``, but when combined with the serde` feature flag, can serve as a way to serialize a quantity, not just the unit.

Variants

AmountOfSubstance(AmountOfSubstance)

Angle(Angle)

Dimensionless(Dimensionless)

ElectricCurrent(ElectricCurrent)

Length(Length)

Luminance(Luminance)

Mass(Mass)

TemperatureInterval(TemperatureInterval)

Time(Time)

Implementations

impl Quantities

pub fn unit(&self) -> Units

Get the Units enumeration associated with a given Quantities enumeration.

pub fn try_convert(&self, unit: Units) -> Result<Quantities, RuntimeUnitError>

Try to convert to the unit specified by a given Units enumeration.

pub fn new(value: f64, unit: Units) -> Quantities

Create a new quantity from a given value and unit

pub fn value(&self) -> f64

Get the value associated with quantity.

Trait Implementations

impl Clone for Quantities

fn clone(&self) -> Quantities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Quantities

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

Formats the value using the given formatter.

impl From<Quantities> for Quantity

fn from(value: Quantities) -> Self

Converts to this type from the input type.

impl From<Units> for Quantities

A means to create a default quantity with a given set of units.

fn from(value: Units) -> Self

Converts to this type from the input type.

impl FromStr for Quantities

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string into a Quantities value.

Format

The expected input format is: <value> <unit>, e.g. "1.1 m".

Errors

Returns an error if the value is missing, the unit is missing, the value cannot be parsed as f64, or the unit is not recognized for any supported quantity.

type Err = RuntimeUnitError

The associated error which can be returned from parsing.

impl PartialEq for Quantities

fn eq(&self, other: &Quantities) -> 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 ToString for Quantities

fn to_string(&self) -> String

Converts the given value to a String.

impl TryFrom<Quantities> for AmountOfSubstance

type Error = RuntimeUnitError
