Struct Unit 

#[non_exhaustive]
pub struct Unit { /* private fields */ }

A unit of measurement that includes a power.

Implementations

impl Unit

pub fn new(quantity: impl Into<Base>) -> Self

Creates a new unit with the given quantity, with power 1.

pub fn with_power(quantity: impl Into<Base>, power: i8) -> Self

Creates a new unit with the given quantity and power.

pub fn conversion_factor(&self, target: Unit) -> Result<f64, ConversionError>

If this unit can be converted to the target unit, returns the conversion factor between them.

Trait Implementations

impl Clone for Unit

fn clone(&self) -> Unit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Unit

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

Formats the value using the given formatter.

impl Display for Unit

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

Formats the value using the given formatter.

impl From<Area> for Unit

fn from(u: Area) -> Self

Converts to this type from the input type.

impl From<Base> for Unit

fn from(q: Base) -> Self

Converts to this type from the input type.

impl From<Length> for Unit

fn from(u: Length) -> Self

Converts to this type from the input type.

impl From<Mass> for Unit

fn from(u: Mass) -> Self

Converts to this type from the input type.

impl From<Time> for Unit

fn from(u: Time) -> Self

Converts to this type from the input type.

impl From<Unit> for CompoundUnit

fn from(u: Unit) -> Self

Converts to this type from the input type.

impl From<Volume> for Unit

fn from(u: Volume) -> Self

Converts to this type from the input type.

impl FromStr for Unit

Try a to convert a string to a Unit.

The string should be in the format <base>[^<power>], where <quantity> is the abbreviation of the quantity (see Base), and <power> is a signed integer representing the power of the unit. If <power> is not specified, it is assumed to be 1.

type Err = InvalidUnit

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this type.

impl PartialEq for Unit

fn eq(&self, other: &Unit) -> 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 TryFrom<&str> for Unit

Try a to convert a string to a Unit.

The string should be in the format <quantity>[^<power>], where <quantity> is the abbreviation of the quantity (see Base), and <power> is the power of the unit. If <power> is not specified, it is assumed to be 1.

type Error = InvalidUnit

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Unit

impl Eq for Unit
