Struct Rational 

pub struct Rational {
    pub num: i32,
    pub den: i32,
}

A rational number num / den.

Fields

num: i32

den: i32

Implementations

impl Rational

pub const ZERO: Rational

pub const fn new(num: i32, den: i32) -> Rational

pub fn as_f64(self) -> f64

Approximate value as f64. Returns NAN for a zero denominator rather than panicking — callers building these from untrusted headers shouldn’t crash on bad input.

pub fn inverse(self) -> Rational

The reciprocal (den / num). Useful to flip a frame rate into a time base.

Trait Implementations

impl Clone for Rational

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Rational

impl Debug for Rational

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

Formats the value using the given formatter.

impl Default for Rational

Defaults to 0/1 (not the derive’s 0/0, which would be a divide-by-zero trap waiting to happen).

fn default() -> Self

Returns the “default value” for a type.

impl Display for Rational

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

Formats the value using the given formatter.

impl Eq for Rational

impl Hash for Rational

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 Rational

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

Equality operator ==.

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

Inequality operator !=.
