[−][src]Struct gdnative::api::WeakRef
core class WeakRef
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
WeakRef inherits methods from:
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 WeakRef
[src]
pub fn new() -> Ref<WeakRef, Unique>
[src]
Creates a new instance of this object.
This is a reference-counted type. The returned object is automatically managed
by Ref
.
pub fn get_ref(&self) -> Variant
[src]
Returns the [Object] this weakref is referring to.
Methods from Deref<Target = Reference>
pub fn init_ref(&self) -> bool
[src]
Initializes the internal reference counter. Use this only if you really know what you are doing.
Returns whether the initialization was successful.
