pub fn as_ptr(&self) -> *mut c_void

pub fn retained_ptr(&self) -> *mut c_void

pub fn deactivate(&self)

Trait Implementations

impl<T: Send + Sync + 'static> Debug for CallbackContext<T>

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

Formats the value using the given formatter.

impl<T: Send + Sync + 'static> Drop for CallbackContext<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
