Type Alias AnchorFunction

pub type AnchorFunction = GenericAnchorFunction<Percentage, LengthPercentage>;

The computed value of an anchor() function.

Aliased Type

struct AnchorFunction {
    pub target_element: DashedIdent,
    pub side: AnchorSide<Percentage>,
    pub fallback: Optional<LengthPercentage>,
}

Fields

target_element: DashedIdent

Anchor name of the element to anchor to. If omitted, selects the implicit anchor element.

side: AnchorSide<Percentage>

Where relative to the target anchor element to position the anchored element to.

fallback: Optional<LengthPercentage>

Value to use in case the anchor function is invalid.

Implementations

impl<Percentage, LengthPercentage> GenericAnchorFunction<Percentage, LengthPercentage>

pub fn resolve<'a>( &'a self, axis: PhysicalAxis, position_property: PositionProperty, ) -> AnchorResolutionResult<'a, LengthPercentage>

Resolve the anchor function. On failure, return reference to fallback, if exists.

Trait Implementations

impl<Percentage, LengthPercentage> Animate for GenericAnchorFunction<Percentage, LengthPercentage>

where Percentage: Animate, LengthPercentage: Animate,

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

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

impl<Percentage: Clone, LengthPercentage: Clone> Clone for GenericAnchorFunction<Percentage, LengthPercentage>

fn clone(&self) -> GenericAnchorFunction<Percentage, LengthPercentage>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Percentage, LengthPercentage> ComputeSquaredDistance for GenericAnchorFunction<Percentage, LengthPercentage>

where Percentage: ComputeSquaredDistance, LengthPercentage: ComputeSquaredDistance,

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

Computes the squared distance between two animatable values.

impl<Percentage: Debug, LengthPercentage: Debug> Debug for GenericAnchorFunction<Percentage, LengthPercentage>

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

Formats the value using the given formatter.

impl<'de, Percentage, LengthPercentage> Deserialize<'de> for GenericAnchorFunction<Percentage, LengthPercentage>

where Percentage: Deserialize<'de>, LengthPercentage: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Percentage, LengthPercentage> MallocSizeOf for GenericAnchorFunction<Percentage, LengthPercentage>

where Percentage: MallocSizeOf, LengthPercentage: 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<Percentage: PartialEq, LengthPercentage: PartialEq> PartialEq for GenericAnchorFunction<Percentage, LengthPercentage>

fn eq( &self, other: &GenericAnchorFunction<Percentage, LengthPercentage>, ) -> 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<Percentage, LengthPercentage> Serialize for GenericAnchorFunction<Percentage, LengthPercentage>

where Percentage: Serialize, LengthPercentage: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<Percentage, LengthPercentage> SpecifiedValueInfo for GenericAnchorFunction<Percentage, LengthPercentage>

where Percentage: SpecifiedValueInfo, LengthPercentage: 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<Percentage, LengthPercentage> ToAnimatedValue for GenericAnchorFunction<Percentage, LengthPercentage>

where Percentage: ToAnimatedValue, LengthPercentage: ToAnimatedValue,

type AnimatedValue = GenericAnchorFunction<<Percentage as ToAnimatedValue>::AnimatedValue, <LengthPercentage as ToAnimatedValue>::AnimatedValue>

where Percentage: ToAnimatedZero, LengthPercentage: 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.
