Trait Implementations

impl<N> Animate for PreferredRatio<N>

where N: Animate, Ratio<N>: Animate,

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

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

impl<N> Clone for PreferredRatio<N>

where N: Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N> ComputeSquaredDistance for PreferredRatio<N>

where N: ComputeSquaredDistance, Ratio<N>: ComputeSquaredDistance,

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

Computes the squared distance between two animatable values.

impl<N> Debug for PreferredRatio<N>

where N: Debug,

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

Formats the value using the given formatter.

impl<N> MallocSizeOf for PreferredRatio<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 for PreferredRatio<N>

where N: PartialEq,

fn eq(&self, other: &PreferredRatio<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 PreferredRatio<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]))

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<N> ToAnimatedValue for PreferredRatio<N>

where N: ToAnimatedValue,

type AnimatedValue = PreferredRatio<<N as ToAnimatedValue>::AnimatedValue>

The type of the animated value.

fn from_animated_value( from: <PreferredRatio<N> as ToAnimatedValue>::AnimatedValue, ) -> PreferredRatio<N>

Converts back an animated value into a computed value.

fn to_animated_value( self, context: &Context<'_>, ) -> <PreferredRatio<N> as ToAnimatedValue>::AnimatedValue

Converts this value to an animated value.

impl<N> ToComputedValue for PreferredRatio<N>

where N: ToComputedValue,

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

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

fn from_computed_value( from: &<PreferredRatio<N> as ToComputedValue>::ComputedValue, ) -> PreferredRatio<N>

Convert a computed value to specified value form.

fn to_computed_value( &self, context: &Context<'_>, ) -> <PreferredRatio<N> as ToComputedValue>::ComputedValue

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

impl<N> ToCss for PreferredRatio<N>

where N: ToCss, Ratio<N>: ToCss,

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

where W: Write,
