Struct Rational

pub struct Rational {
    pub numerator: i32,
    pub denominator: NonZero<i32>,
}

A rational number.

Fields

numerator: i32

Numerator.

denominator: NonZero<i32>

Denominator.

Implementations

impl Rational

pub const ONE: Rational

The one rational number.

pub const ZERO: Rational

The zero rational number.

pub const fn new(numerator: i32, denominator: NonZero<i32>) -> Self

Create a new rational number.

pub const fn static_new<const N: i32, const D: i32>() -> Self

Construct a new rational number at compile time.

Panics

This will panic if the denominator is 0.

pub fn as_f64(&self) -> f64

Get the rational number as a floating point number.

pub fn from_f64_rounded(value: f64) -> Self

Create a new rational number from a floating point number. The number might be truncated.

Trait Implementations

impl Clone for Rational

fn clone(&self) -> Rational

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rational

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

Formats the value using the given formatter.

impl Default for Rational

fn default() -> Self

Returns the “default value” for a type.

impl From<AVRational> for Rational

fn from(rational: AVRational) -> Self

Converts to this type from the input type.

impl From<Rational> for AVRational

fn from(rational: Rational) -> Self

Converts to this type from the input type.

impl From<Rational> for f32

fn from(rational: Rational) -> Self

Converts to this type from the input type.

impl From<Rational> for f64

fn from(rational: Rational) -> Self

Converts to this type from the input type.

impl From<i32> for Rational

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for Rational

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