Trait Export
pub trait Export: Var {
// Provided methods
fn export_hint() -> PropertyHintInfo { ... }
fn as_node_class() -> Option<ClassName> { ... }
}Expand description
Trait implemented for types that can be used as #[export] fields.
Export is only implemented for objects Gd<T> if either T: Inherits<Node> or T: Inherits<Resource>, just like GDScript.
This means you cannot use #[export] with Gd<RefCounted>, for example.
Provided Methods§
fn export_hint() -> PropertyHintInfo
fn export_hint() -> PropertyHintInfo
The export info to use for an exported field of this type, if no other export info is specified.
fn as_node_class() -> Option<ClassName>
fn as_node_class() -> Option<ClassName>
If this is a class inheriting Node, returns the ClassName; otherwise None.
Only overridden for Gd<T>, to detect erroneous exports of Node inside a Resource class.
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.
