Struct style::values::generics::position::GenericAnchorFunction

#[repr(C)]
pub struct GenericAnchorFunction<Percentage, LengthPercentage> {
    pub target_element: DashedIdent,
    pub side: AnchorSide<Percentage>,
    pub fallback: Optional<LengthPercentage>,
}

Anchor function used by inset properties. This resolves to length at computed time.

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.

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<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

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<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>

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<Percentage, LengthPercentage> ToAnimatedZero for GenericAnchorFunction<Percentage, LengthPercentage>

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.

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

where Percentage: ToComputedValue, LengthPercentage: ToComputedValue,

type ComputedValue = GenericAnchorFunction<<Percentage as ToComputedValue>::ComputedValue, <LengthPercentage 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<Percentage, LengthPercentage> ToCss for GenericAnchorFunction<Percentage, LengthPercentage>

where Percentage: ToCss, LengthPercentage: 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<Percentage, LengthPercentage> ToResolvedValue for GenericAnchorFunction<Percentage, LengthPercentage>

where Percentage: ToResolvedValue, LengthPercentage: ToResolvedValue,

type ResolvedValue = GenericAnchorFunction<<Percentage as ToResolvedValue>::ResolvedValue, <LengthPercentage as ToResolvedValue>::ResolvedValue>

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

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

Convert a resolved value to resolved value form.

fn to_resolved_value(self, context: &Context<'_>) -> Self::ResolvedValue

Convert a resolved value to a resolved value.

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

where Percentage: ToShmem, LengthPercentage: ToShmem,

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.
