Trait Implementations

impl<H, V> Animate for GenericPosition<H, V>

where H: Animate, V: Animate,

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

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

impl<H: Clone, V: Clone> Clone for GenericPosition<H, V>

fn clone(&self) -> GenericPosition<H, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<H, V> ComputeSquaredDistance for GenericPosition<H, V>

where H: ComputeSquaredDistance, V: ComputeSquaredDistance,

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

Computes the squared distance between two animatable values.

impl<H: Debug, V: Debug> Debug for GenericPosition<H, V>

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

Formats the value using the given formatter.

impl<'de, H, V> Deserialize<'de> for GenericPosition<H, V>

where H: Deserialize<'de>, V: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<H, V> MallocSizeOf for GenericPosition<H, V>

where H: MallocSizeOf, V: 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 GenericPosition<Component<X>, Component<Y>>

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

Parse a value of this type.

impl<H: PartialEq, V: PartialEq> PartialEq for GenericPosition<H, V>

fn eq(&self, other: &GenericPosition<H, V>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<H, V> PositionComponent for Position<H, V>

where H: PositionComponent, V: PositionComponent,

fn is_center(&self) -> bool

Returns if the position component is 50% or center. For pixel lengths, it always returns false.

impl<H, V> Serialize for GenericPosition<H, V>

where H: Serialize, V: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<H, V> SpecifiedValueInfo for GenericPosition<H, V>

where H: SpecifiedValueInfo, V: 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<H, V> ToAnimatedValue for GenericPosition<H, V>

where H: ToAnimatedValue, V: ToAnimatedValue,

type AnimatedValue = GenericPosition<<H as ToAnimatedValue>::AnimatedValue, <V 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.

where H: ToAnimatedZero, V: 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.
