Struct Conversion 

pub struct Conversion { /* private fields */ }

A value with a known source unit, ready to convert.

Implementations

impl Conversion

pub fn to(&self, unit: &str) -> Result<f64, Error>

Convert to the destination unit.

Errors

Returns Error::UnsupportedUnit if unit is unknown, or Error::IncompatibleMeasures if it measures something different from the source.

pub fn to_best(&self) -> Option<Best>

Convert to the most appropriate unit (the smallest value ≥ 1 in the source system).

pub fn to_best_with(&self, exclude: &[&str], cut_off: f64) -> Option<Best>

Like to_best, excluding units in exclude and using cut_off as the lower bound a candidate value must reach.

pub fn possibilities(&self) -> Vec<&'static str>

The unit abbreviations the source value can be converted to (its measure’s units).

pub fn describe_origin(&self) -> UnitInfo

Metadata about the source unit.

Trait Implementations

impl Clone for Conversion

fn clone(&self) -> Conversion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Conversion

impl Debug for Conversion

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

Formats the value using the given formatter.
