Struct BasicNumber

pub struct BasicNumber { /* private fields */ }

A Haystack Number, encapsulating a scalar value and an optional unit value. The unit is represented as a string. This does not represent Haystack scientific notation numbers.

Implementations

impl BasicNumber

pub fn new(value: f64, unit: Option<String>) -> BasicNumber

Create a new BasicNumber. If present, the unit should be a valid unit string from Project Haystack’s unit database.

pub fn new_unitless(value: f64) -> BasicNumber

Create a new BasicNumber with no unit.

pub fn value(&self) -> f64

Return the numeric component of this number.

pub fn unit(&self) -> Option<&str>

Return the unit component of this number, if present.

pub fn to_axon_code(&self) -> String

Return a string containing Axon code representing this number.

Trait Implementations

impl Clone for BasicNumber

fn clone(&self) -> BasicNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BasicNumber

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

Formats the value using the given formatter.

impl Display for BasicNumber

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

Formats the value using the given formatter.

impl PartialEq for BasicNumber

fn eq(&self, other: &BasicNumber) -> 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.
