filters: Vec<FilterOp>

CSS filters to be applied to this stacking context (including opacity).

mix_blend_mode: MixBlendMode

The blend mode with which this stacking context blends with its backdrop.

transform: Option<LayoutTransform>

A transform to be applied to this stacking context.

transform_style: TransformStyle

The transform style of this stacking context.

perspective: Option<LayoutTransform>

The perspective matrix to be applied to children.

parent_clipping_and_scrolling: ClippingAndScrolling

Implementations

impl StackingContext

pub fn new( id: StackingContextId, context_type: StackingContextType, bounds: LayoutRect, overflow: LayoutRect, z_index: i32, in_top_layer: InTopLayer, filters: Vec<FilterOp>, mix_blend_mode: MixBlendMode, transform: Option<LayoutTransform>, transform_style: TransformStyle, perspective: Option<LayoutTransform>, parent_clipping_and_scrolling: ClippingAndScrolling, established_reference_frame: Option<ClipScrollNodeIndex>, ) -> StackingContext

Creates a new stacking context.

pub fn root() -> StackingContext

pub fn to_display_list_items(self) -> (DisplayItem, DisplayItem)

Trait Implementations

impl Clone for StackingContext

fn clone(&self) -> StackingContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StackingContext

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

Formats the value using the given formatter.

impl Ord for StackingContext

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for StackingContext

fn eq(&self, other: &Self) -> 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 PartialOrd for StackingContext

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for StackingContext

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
