Implementations

impl<LengthPercentage> BackgroundSize<LengthPercentage>

pub fn auto() -> Self

Returns auto auto.

Trait Implementations

impl<LengthPercent> Animate for GenericBackgroundSize<LengthPercent>

where LengthPercent: Animate,

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

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

impl<LengthPercent: Clone> Clone for GenericBackgroundSize<LengthPercent>

fn clone(&self) -> GenericBackgroundSize<LengthPercent>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<LengthPercent> ComputeSquaredDistance for GenericBackgroundSize<LengthPercent>

where LengthPercent: ComputeSquaredDistance,

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

Computes the squared distance between two animatable values.

impl<LengthPercent: Debug> Debug for GenericBackgroundSize<LengthPercent>

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

Formats the value using the given formatter.

impl<LengthPercent> MallocSizeOf for GenericBackgroundSize<LengthPercent>

where LengthPercent: 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<LengthPercent: PartialEq> PartialEq for GenericBackgroundSize<LengthPercent>

fn eq(&self, other: &GenericBackgroundSize<LengthPercent>) -> 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<LengthPercent> SpecifiedValueInfo for GenericBackgroundSize<LengthPercent>

where LengthPercent: 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<LengthPercent> ToAnimatedValue for GenericBackgroundSize<LengthPercent>

where LengthPercent: ToAnimatedValue,

type AnimatedValue = GenericBackgroundSize<<LengthPercent as ToAnimatedValue>::AnimatedValue>

The type of the animated value.

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<LengthPercent> ToAnimatedZero for GenericBackgroundSize<LengthPercent>

where LengthPercent: ToAnimatedZero,

fn to_animated_zero(&self) -> Result<Self, ()>

Returns a value that, when added with an underlying value, will produce the underlying value. This is used for SMIL animation’s “by-animation” where SMIL first interpolates from the zero value to the ‘by’ value, and then adds the result to the underlying value.

impl<LengthPercent> ToComputedValue for GenericBackgroundSize<LengthPercent>

where LengthPercent: ToComputedValue,

type ComputedValue = GenericBackgroundSize<<LengthPercent 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<LengthPercent> ToCss for GenericBackgroundSize<LengthPercent>

where LengthPercent: ToCss,

where W: Write,

Serialize self in CSS syntax, writing to dest.
