Trait Implementations

impl AsRef<RenderNode> for OpacityNode

fn as_ref(&self) -> &RenderNode

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for OpacityNode

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the reference. Dropping the reference will decrement it again.

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

Performs copy-assignment from source.

impl Debug for OpacityNode

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

Formats the value using the given formatter.

impl Deref for OpacityNode

type Target = RenderNode

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> FromValue<'a> for OpacityNode

Available on crate feature v4_6 only.

type Checker = GenericValueTypeOrNoneChecker<OpacityNode>

Value type checker.

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

Get the contained value from a Value.

impl IsRenderNode for OpacityNode

const NODE_TYPE: RenderNodeType = RenderNodeType::OpacityNode

fn upcast(self) -> RenderNode

fn upcast_ref(&self) -> &RenderNode

impl StaticType for OpacityNode

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for OpacityNode

Available on crate feature v4_6 only.

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ToValueOptional for OpacityNode

Available on crate feature v4_6 only.

fn to_value_optional(s: Option<&Self>) -> Value

Convert an Option to a Value.

impl ValueType for OpacityNode

Available on crate feature v4_6 only.

type Type = OpacityNode

Type to get the Type from.
