Struct DASession 

pub struct DASession { /* private fields */ }

Available on crate feature DASession only.

Type of a reference to DASession instances.

See also Apple’s documentation

Implementations

impl DASession

pub unsafe fn new( allocator: Option<&CFAllocator>, ) -> Option<CFRetained<DASession>>

Creates a new session.

Returns: A reference to a new DASession.

The caller of this function receives a reference to the returned object. The caller also implicitly retains the object and is responsible for releasing it.

pub unsafe fn schedule_with_run_loop( &self, run_loop: &CFRunLoop, run_loop_mode: &CFString, )

Schedules the session on a run loop.

Parameter session: The session which is being scheduled.

Parameter runLoop: The run loop on which the session should be scheduled.

Parameter runLoopMode: The run loop mode in which the session should be scheduled.

Safety

run_loop possibly has additional threading requirements.

pub unsafe fn unschedule_from_run_loop( &self, run_loop: &CFRunLoop, run_loop_mode: &CFString, )

Unschedules the session from a run loop.

Parameter session: The session which is being unscheduled.

Parameter runLoop: The run loop on which the session is scheduled.

Parameter runLoopMode: The run loop mode in which the session is scheduled.

Safety

run_loop possibly has additional threading requirements.

pub unsafe fn set_dispatch_queue(&self, queue: Option<&DispatchQueue>)

Available on crate feature dispatch2 only.

Schedules the session on a dispatch queue.

Parameter session: The session which is being scheduled.

Parameter queue: The dispatch queue on which the session should be scheduled. Pass NULL to unschedule.

Safety

queue possibly has additional threading requirements.

Methods from Deref<Target = CFType>

pub fn downcast_ref<T>(&self) -> Option<&T>

where T: ConcreteType,

Attempt to downcast the type to that of type T.

This is the reference-variant. Use CFRetained::downcast if you want to convert a retained type. See also ConcreteType for more details on which types support being converted to.

pub fn retain_count(&self) -> usize

Get the reference count of the object.

This function may be useful for debugging. You normally do not use this function otherwise.

Beware that some things (like CFNumbers, small CFStrings etc.) may not have a normal retain count for optimization purposes, and can return usize::MAX in that case.

Trait Implementations

impl AsRef<AnyObject> for DASession

fn as_ref(&self) -> &AnyObject

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<CFType> for DASession

fn as_ref(&self) -> &CFType

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<DASession> for DASession

fn as_ref(&self) -> &Self

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<AnyObject> for DASession

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for DASession

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for DASession

fn type_id() -> CFTypeID

Returns the type identifier of all DASession instances.

impl Debug for DASession

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

Formats the value using the given formatter.

impl Deref for DASession

type Target = CFType

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for DASession

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for DASession

fn retain(&self) -> Retained<Self>

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for DASession

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RefEncode for DASession

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Type for DASession

fn retain(&self) -> CFRetained<Self>

where Self: Sized,

Increment the reference count of the receiver.
