[−][src]Struct objc::rc::StrongPtr
A pointer that strongly references an object, ensuring it won't be deallocated.
Implementations
impl StrongPtr
[src]
pub unsafe fn new(ptr: *mut Object) -> Self
[src]
Constructs a StrongPtr
to a newly created object that already has a
+1 retain count. This will not retain the object.
When dropped, the object will be released.
Unsafe because the caller must ensure the given object pointer is valid.
pub unsafe fn retain(ptr: *mut Object) -> Self
[src]
Retains the given object and constructs a StrongPtr
to it.
When dropped, the object will be released.
Unsafe because the caller must ensure the given object pointer is valid.
pub fn autorelease(self) -> *mut Object
[src]
Autoreleases self, meaning that the object is not immediately released, but will be when the autorelease pool is drained. A pointer to the object is returned, but its validity is no longer ensured.
pub fn weak(&self) -> WeakPtr
[src]
Returns a WeakPtr
to self.
