Trait GodotDefault

Source 
pub trait GodotDefault: GodotClass { }
Expand description

Trait for all classes that are default-constructible from the Godot engine.

Enables the MyClass.new() syntax in GDScript, and allows the type to be used by the editor, which often default-constructs objects.

This trait is automatically implemented for the following classes:

  • User defined classes if either:
    • they override an init() method
    • they have #[class(init)] attribute
  • Engine classes if:
    • they are reference-counted and constructible (i.e. provide a new() method).

This trait is not manually implemented, and you cannot call any methods. You can use it as a bound, but typically you’d use it indirectly through Gd::default(). Note that Gd::default() has an additional requirement on being reference-counted, meaning not every GodotDefault class can automatically be used with Gd::default().

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
