}Expand description
Trait implemented for types that can be used as #[var] fields.
This creates a copy of the value, according to copy semantics provided by Clone. For example, Array, Dictionary and Gd are
returned by shared reference instead of copying the actual data.
This does not require FromGodot or ToGodot, so that something can be used as a property even if it can’t be used in function
arguments/return types.
See also Export, a specialization of this trait for properties exported to the editor UI.
For enums, this trait can be derived using the #[derive(Var)] macro.
Required Methods§
fn get_property(&self) -> Self::Via
fn set_property(&mut self, value: Self::Via)
Provided Methods§
fn var_hint() -> PropertyHintInfo
fn var_hint() -> PropertyHintInfo
Specific property hints, only override if they deviate from GodotType::property_info, e.g. for enums/newtypes.
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.
