pub type Ratio = Ratio<NonNegativeNumber>;
Expand description

A computed value.

Aliased Type§

struct Ratio(pub NonNegative<f32>, pub NonNegative<f32>);

Fields§

§0: NonNegative<f32>§1: NonNegative<f32>

Implementations§

source§

impl Ratio

source

pub fn new(a: f32, b: f32) -> Self

Returns a new Ratio.

source

pub fn used_value(self) -> Self

Returns the used value. A ratio of 0/0 behaves as the ratio 1/0. https://drafts.csswg.org/css-values-4/#ratios

source

pub fn is_degenerate(&self) -> bool

Returns true if this is a degenerate ratio. https://drafts.csswg.org/css-values/#degenerate-ratio

source

fn to_f32(&self) -> f32

Returns the f32 value by dividing the first value by the second one.
