Struct Fraction64 

pub struct Fraction64 { /* private fields */ }

Represents a fraction value.

This is an f64 value under the hood, which is in 0.0 .. 1.0 range.

Implementations

impl Fraction64

pub const unsafe fn new_unchecked(value: f64) -> Self

Creates a new Fraction64 instance out of passed value.

Safety

This function does not verify that value is in the expected 0.0 .. 1.0 range.

pub const fn new(value: f64) -> Result<Self, FractionError>

Creates a new Fraction64 instance out of passed value.

Errors

Return FractionError::NotAFraction if the passed value is outside of 0.0 .. 1.0 range.

pub const fn value(&self) -> f64

Returns the underlying f64 value.

Trait Implementations

impl Clone for Fraction64

fn clone(&self) -> Fraction64

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fraction64

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

Formats the value using the given formatter.

impl PartialEq for Fraction64

fn eq(&self, other: &Fraction64) -> 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 PartialOrd for Fraction64

fn partial_cmp(&self, other: &Fraction64) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
