Struct SharedEvent 

pub struct SharedEvent(/* private fields */);

A cross-process synchronization primitive.

C++ equivalent: MTL::SharedEvent

Implementations

impl SharedEvent

pub unsafe fn from_raw(ptr: *mut c_void) -> Option<Self>

Create a SharedEvent from a raw pointer.

Safety

The pointer must be a valid Metal shared event object.

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

Get the raw pointer.

pub fn label(&self) -> Option<String>

Get the label.

C++ equivalent: NS::String* label() const

pub fn set_label(&self, label: &str)

Set the label.

C++ equivalent: void setLabel(const NS::String*)

pub fn device(&self) -> Device

Get the device.

C++ equivalent: Device* device() const

pub fn signaled_value(&self) -> u64

Get the current signaled value.

C++ equivalent: uint64_t signaledValue() const

pub fn set_signaled_value(&self, value: u64)

Set the signaled value.

C++ equivalent: void setSignaledValue(uint64_t)

pub fn new_shared_event_handle(&self) -> Option<SharedEventHandle>

Create a handle for sharing across processes.

C++ equivalent: SharedEventHandle* newSharedEventHandle()

pub unsafe fn notify_listener<F>( &self, listener: *const c_void, value: u64, block: F, )

where F: Fn(*mut c_void, u64) + Send + 'static,

Notify a listener when the event reaches a value.

C++ equivalent: void notifyListener(SharedEventListener*, uint64_t, void (^)(SharedEvent*, uint64_t))

Safety

The listener pointer must be valid.

Trait Implementations

impl Clone for SharedEvent

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SharedEvent

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

impl Referencing for SharedEvent

fn as_ptr(&self) -> *const c_void

Get the raw pointer to the Objective-C object.

fn as_mut_ptr(&self) -> *mut c_void

fn retain(&self) -> Self

where Self: Clone,

Retain the object, incrementing its reference count.

fn release(&self)

Release the object, decrementing its reference count.

fn autorelease(&self) -> Self

where Self: Clone,

Autorelease the object.

fn retain_count(&self) -> usize

Get the retain count of the object.
