Struct makepad_objc_sys::rc::StrongPtr

pub struct StrongPtr(_);

A pointer that strongly references an object, ensuring it won’t be deallocated.

Implementations

impl StrongPtr

pub unsafe fn new(ptr: *mut Object) -> Self

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

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

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

Returns a WeakPtr to self.

impl Deref for StrongPtr

type Target = *mut Object

fn deref(&self) -> &*mut Object

Dereferences the value.

impl Drop for StrongPtr

fn drop(&mut self)

impl Pointer for StrongPtr

fn fmt(&self, f: &mut Formatter<'_>) -> Result
