Enum Number

pub enum Number {
    Basic(BasicNumber),
    Scientific(ScientificNumber),
}

A Haystack number.

Variants

Basic(BasicNumber)

Scientific(ScientificNumber)

Implementations

impl Number

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

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

pub fn new_unitless(value: f64) -> Self

Create a new Number and no unit.

pub fn new_scientific( significand: f64, exponent: i32, unit: Option<String>, ) -> Option<Self>

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

pub fn new_scientific_unitless(significand: f64, exponent: i32) -> Option<Self>

Create a new scientific notation Number and no unit.

pub fn as_number(&self) -> Option<&BasicNumber>

If this represents a non-scientific notation number, return the number.

pub fn as_scientific_number(&self) -> Option<&ScientificNumber>

If this represents a number in scientific notation, return the scientific notation 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 Number

fn clone(&self) -> Number

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Number

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

Formats the value using the given formatter.

impl Display for Number

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

Formats the value using the given formatter.

impl PartialEq for Number

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