Struct RationalValue 

pub struct RationalValue { /* private fields */ }

An exact normalized rational number.

Implementations

impl RationalValue

pub fn new(numerator: i64, denominator: u64) -> Result<Self>

Creates a rational value reduced to lowest terms.

Errors

Returns ErrorKind::InvalidArgument when denominator is zero.

pub const fn numerator(self) -> i64

Returns the normalized numerator.

pub const fn denominator(self) -> u64

Returns the positive normalized denominator.

Trait Implementations

impl Clone for RationalValue

fn clone(&self) -> RationalValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RationalValue

impl Debug for RationalValue

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

Formats the value using the given formatter.

impl Eq for RationalValue

impl Hash for RationalValue

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RationalValue

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