Struct sp_arithmetic::rational::RationalInfinite

pub struct RationalInfinite(/* private fields */);

A wrapper for any rational number with infinitely large numerator and denominator.

This type exists to facilitate cmp operation on values like a/b < c/d where a, b, c, d are all BigUint.

Implementations

impl RationalInfinite

pub fn n(&self) -> &BigUint

Return the numerator reference.

pub fn d(&self) -> &BigUint

Return the denominator reference.

pub fn from(n: BigUint, d: BigUint) -> Self

Build from a raw n/d.

pub fn zero() -> Self

Zero.

pub fn one() -> Self

One.

Trait Implementations

impl Clone for RationalInfinite

fn clone(&self) -> RationalInfinite

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for RationalInfinite

fn default() -> RationalInfinite

Returns the “default value” for a type.

impl From<Rational128> for RationalInfinite

fn from(t: Rational128) -> Self

Converts to this type from the input type.

impl Ord for RationalInfinite

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for RationalInfinite

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RationalInfinite

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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