Struct gdnative_bindings::Expression

pub struct Expression { /* fields omitted */ }

core class Expression inherits Reference (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

Expression inherits methods from:

• Reference
• Object

Methods

impl Expression

pub fn new() -> Self

pub fn new_ref(&self) -> Self

Creates a new reference to the same reference-counted object.

pub fn execute(
    &mut self,
    inputs: VariantArray,
    base_instance: Option<Object>,
    show_error: bool
) -> Variant

pub fn get_error_text(&self) -> GodotString

pub fn has_execute_failed(&self) -> bool

pub fn parse(
    &mut self,
    expression: GodotString,
    input_names: StringArray
) -> GodotResult

pub fn init_ref(&mut self) -> bool

Inherited from Reference.

pub fn to_reference(&self) -> Reference

Up-cast.

pub fn to_object(&self) -> Object

Up-cast.

pub fn cast<T: GodotObject>(&self) -> Option<T>

Generic dynamic cast.

Methods from Deref<Target = Reference>

pub fn new_ref(&self) -> Reference

pub fn init_ref(&mut self) -> bool

pub fn to_object(&self) -> Object

Up-cast.

pub fn cast<T>(&self) -> Option<T> where
    T: GodotObject,
