Type Alias Ratio

pub type Ratio = Ratio<NonNegativeNumber>;

A specified value.

Aliased Type

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

Fields

0: NonNegative<Number>

1: NonNegative<Number>

Implementations

impl<N> Ratio<N>

where N: Zero + One,

pub fn is_degenerate(&self) -> bool

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

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

Trait Implementations

impl Parse for Ratio

fn parse<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't>, ) -> Result<Self, ParseError<'i>>

Parse a value of this type.

impl<N: Clone> Clone for Ratio<N>

fn clone(&self) -> Ratio<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Debug> Debug for Ratio<N>

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

Formats the value using the given formatter.

impl<N> MallocSizeOf for Ratio<N>

where N: MallocSizeOf,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<N: PartialEq> PartialEq for Ratio<N>

fn eq(&self, other: &Ratio<N>) -> 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.

impl<N> SpecifiedValueInfo for Ratio<N>

where N: SpecifiedValueInfo,

const SUPPORTED_TYPES: u8

Supported CssTypes by the given value type.

fn collect_completion_keywords(_f: &mut dyn FnMut(&[&'static str]))

type ComputedValue = Ratio<<N as ToComputedValue>::ComputedValue>

The computed value type we’re going to be converted to.

fn from_computed_value(from: &Self::ComputedValue) -> Self
