Struct gdnative::api::VisualShaderNodeGlobalExpression

pub struct VisualShaderNodeGlobalExpression { /* fields omitted */ }

core class VisualShaderNodeGlobalExpression inherits VisualShaderNodeExpression (reference counted).

Official documentation

See the documentation of this class in the Godot engine's official documentation.

Memory management

The lifetime of this object is automatically managed through reference counting.

Class hierarchy

VisualShaderNodeGlobalExpression inherits methods from:

• VisualShaderNodeExpression
• VisualShaderNodeGroupBase
• VisualShaderNode
• Resource
• Reference
• Object

Safety

All types in the Godot API have "interior mutability" in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

impl VisualShaderNodeGlobalExpression

pub fn new() -> Ref<VisualShaderNodeGlobalExpression, Unique>

Creates a new instance of this object.

This is a reference-counted type. The returned object is automatically managed by Ref.

Methods from Deref<Target = VisualShaderNodeExpression>

pub fn expression(&self) -> GodotString

An expression in Godot Shading Language, which will be injected at the start of the graph's matching shader function ([code]vertex[/code], [code]fragment[/code], or [code]light[/code]), and thus cannot be used to declare functions, varyings, uniforms, or global constants.

pub fn set_expression(&self, expression: impl Into<GodotString>)

An expression in Godot Shading Language, which will be injected at the start of the graph's matching shader function ([code]vertex[/code], [code]fragment[/code], or [code]light[/code]), and thus cannot be used to declare functions, varyings, uniforms, or global constants.

Trait Implementations

impl Debug for VisualShaderNodeGlobalExpression

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

Formats the value using the given formatter.

impl Deref for VisualShaderNodeGlobalExpression

type Target = VisualShaderNodeExpression

The resulting type after dereferencing.

fn deref(&self) -> &VisualShaderNodeExpression

Dereferences the value.

impl DerefMut for VisualShaderNodeGlobalExpression

fn deref_mut(&mut self) -> &mut VisualShaderNodeExpression

Mutably dereferences the value.

impl GodotObject for VisualShaderNodeGlobalExpression

type RefKind = RefCounted

The memory management kind of this type. This modifies the behavior of the Ref smart pointer. See its type-level documentation for more information.

fn class_name() -> &'static str

fn null() -> Null<Self>

Creates an explicitly null reference of Self as a method argument. This makes type inference easier for the compiler compared to Option.

fn new() -> Ref<Self, Unique> where
    Self: Instanciable, 

Creates a new instance of Self using a zero-argument constructor, as a Unique reference.

fn cast<T>(&self) -> Option<&T> where
    T: GodotObject + SubClass<Self>, 

Performs a dynamic reference downcast to target type.

fn upcast<T>(&self) -> &T where
    Self: SubClass<T>,
    T: GodotObject, 

Performs a static reference upcast to a supertype that is guaranteed to be valid.

unsafe fn assume_shared(&self) -> Ref<Self, Shared>

Creates a persistent reference to the same Godot object with shared thread access.

unsafe fn assume_thread_local(&self) -> Ref<Self, ThreadLocal> where
    Self: GodotObject<RefKind = RefCounted>, 

Creates a persistent reference to the same Godot object with thread-local thread access.

unsafe fn assume_unique(&self) -> Ref<Self, Unique>

Creates a persistent reference to the same Godot object with unique access.
