value: Number

The actual value.

Trait Implementations

impl<Number> Animate for VariationValue<Number>

where Number: Animate,

fn animate(&self, other: &Self, procedure: Procedure) -> Result<Self, ()>

Animate a value towards another one, given an animation procedure.

impl<Number: Clone> Clone for VariationValue<Number>

fn clone(&self) -> VariationValue<Number>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Number> ComputeSquaredDistance for VariationValue<Number>

where Number: ComputeSquaredDistance,

fn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>

Computes the squared distance between two animatable values.

impl<Number: Debug> Debug for VariationValue<Number>

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

Formats the value using the given formatter.

impl<Number> MallocSizeOf for VariationValue<Number>

where Number: 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 Parse for VariationValue<Number>

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

This is the <string> <number> part of the font-variation-settings syntax.

impl<Number: PartialEq> PartialEq for VariationValue<Number>

fn eq(&self, other: &VariationValue<Number>) -> 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<Number> SpecifiedValueInfo for VariationValue<Number>

where Number: SpecifiedValueInfo,

const SUPPORTED_TYPES: u8 = _

Supported CssTypes by the given value type.

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

Collect value starting words for the given specified value type. This includes keyword and function names which can appear at the beginning of a value of this type.

impl<T> TaggedFontValue for VariationValue<T>

fn tag(&self) -> FontTag

The value’s tag.

impl<Number> ToAnimatedValue for VariationValue<Number>

where Number: ToAnimatedValue,

type AnimatedValue = VariationValue<<Number as ToAnimatedValue>::AnimatedValue>

fn from_animated_value(from: Self::AnimatedValue) -> Self

Converts back an animated value into a computed value.

fn to_animated_value(self, context: &Context<'_>) -> Self::AnimatedValue

Converts this value to an animated value.

impl<Number> ToComputedValue for VariationValue<Number>

where Number: ToComputedValue,

type ComputedValue = VariationValue<<Number as ToComputedValue>::ComputedValue>

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

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

Convert a computed value to specified value form.

fn to_computed_value(&self, context: &Context<'_>) -> Self::ComputedValue

Convert a specified value to a computed value, using itself and the data inside the Context.

impl<Number> ToCss for VariationValue<Number>

where Number: ToCss,

fn to_css<W>(&self, dest: &mut CssWriter<'_, W>) -> Result

where W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.

impl<Number> ToResolvedValue for VariationValue<Number>

where Number: ToResolvedValue,

type ResolvedValue = VariationValue<<Number as ToResolvedValue>::ResolvedValue>

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

fn from_resolved_value(from: Self::ResolvedValue) -> Self
