The type of a node determines what the node is rendering.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotARenderNode

Error type. No node will ever have this type.

ContainerNode

A node containing a stack of children

CairoNode

A node drawing a [cairo::Surface][crate::cairo::Surface]

ColorNode

A node drawing a single color rectangle

LinearGradientNode

A node drawing a linear gradient

RepeatingLinearGradientNode

A node drawing a repeating linear gradient

RadialGradientNode

A node drawing a radial gradient

RepeatingRadialGradientNode

A node drawing a repeating radial gradient

ConicGradientNode

A node drawing a conic gradient

BorderNode

A node stroking a border around an area

TextureNode

A node drawing a gdk::Texture

InsetShadowNode

A node drawing an inset shadow

OutsetShadowNode

A node drawing an outset shadow

TransformNode

A node that renders its child after applying a matrix transform

OpacityNode

A node that changes the opacity of its child

ColorMatrixNode

A node that applies a color matrix to every pixel

RepeatNode

A node that repeats the child’s contents

ClipNode

A node that clips its child to a rectangular area

RoundedClipNode

A node that clips its child to a rounded rectangle

ShadowNode

A node that draws a shadow below its child

BlendNode

A node that blends two children together

CrossFadeNode

A node that cross-fades between two children

TextNode

A node containing a glyph string

BlurNode

A node that applies a blur

DebugNode

Debug information that does not affect the rendering

GlShaderNode

A node that uses OpenGL fragment shaders to render

TextureScaleNode

A node drawing a gdk::Texture scaled and filtered.

MaskNode

A node that masks one child with another.

FillNode

A node that fills a path.

StrokeNode

A node that strokes a path.

SubsurfaceNode

A node that possibly redirects part of the scene graph to a subsurface.

ComponentTransferNode

A node that applies some function to each color component.

CopyNode

A node that copies the rendering canvas to be pasted later.

PasteNode

A node that pastes a previously copied canvas.

CompositeNode

A node that combines a child with the background using Porter/Duff operations.

IsolationNode

A node that isolated content of its child from previous content.

DisplacementNode

A node that displaces content according to some mask.

ArithmeticNode

A node that combines two child nodes in an arithmetic way.

TurbulenceNode

A node that generates a Perlin noise or fractal Brownian motion pattern.

Trait Implementations

impl Clone for RenderNodeType

fn clone(&self) -> RenderNodeType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RenderNodeType

impl Debug for RenderNodeType

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

Formats the value using the given formatter.

impl Eq for RenderNodeType

impl From<RenderNodeType> for Value

fn from(v: RenderNodeType) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for RenderNodeType

type Checker = GenericValueTypeChecker<RenderNodeType>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for RenderNodeType

type ParamSpec = ParamSpecEnum

type SetValue = RenderNodeType

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str, RenderNodeType) -> ParamSpecEnumBuilder<'_, RenderNodeType>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for RenderNodeType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,
