Struct SCPickerSubscription 

pub struct SCPickerSubscription { /* private fields */ }

Handle representing a live repeating-observer registration.

The observer is removed when this value is dropped. Call Self::detach to keep the observer alive for the rest of the process.

Implementations

impl SCPickerSubscription

pub const fn token(&self) -> i64

Opaque identifier for this registration. Non-zero when registration succeeded.

pub fn is_active(&self) -> bool

Whether this subscription refers to a live registration.

pub fn unsubscribe(self) -> bool

Remove the observer now instead of waiting for the drop.

Returns true if a live observer was removed.

pub fn detach(self)

Give up ownership without removing the observer, keeping it registered for the remainder of the process.

Useful for “install once at startup” wiring where there is no natural owner for the handle. The registration can still be torn down with SCContentSharingPicker::remove_all_observers.

Trait Implementations

impl Debug for SCPickerSubscription

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

Formats the value using the given formatter.

impl Drop for SCPickerSubscription

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.
