Struct CFMessagePort 

pub struct CFMessagePort { /* private fields */ }

Available on crate feature CFMessagePort only.

Apple’s documentation

This is toll-free bridged with NSMessagePort.

Implementations

impl CFMessagePort

pub unsafe fn new_local( allocator: Option<&CFAllocator>, name: Option<&CFString>, callout: CFMessagePortCallBack, context: *mut CFMessagePortContext, should_free_info: *mut u8, ) -> Option<CFRetained<CFMessagePort>>

Available on crate feature CFData only.

Safety

• allocator might not allow None.
• name might not allow None.
• callout must be implemented correctly.
• context must be a valid pointer.
• should_free_info must be a valid pointer.

pub fn new_remote( allocator: Option<&CFAllocator>, name: Option<&CFString>, ) -> Option<CFRetained<CFMessagePort>>

pub fn is_remote(&self) -> bool

pub fn name(&self) -> Option<CFRetained<CFString>>

pub fn set_name(&self, new_name: Option<&CFString>) -> bool

pub unsafe fn context(&self, context: *mut CFMessagePortContext)

Safety

context must be a valid pointer.

pub fn invalidate(&self)

pub fn is_valid(&self) -> bool

pub fn invalidation_call_back(&self) -> CFMessagePortInvalidationCallBack

pub unsafe fn set_invalidation_call_back( &self, callout: CFMessagePortInvalidationCallBack, )

Safety

callout must be implemented correctly.

pub unsafe fn send_request( &self, msgid: i32, data: Option<&CFData>, send_timeout: CFTimeInterval, rcv_timeout: CFTimeInterval, reply_mode: Option<&CFString>, return_data: *mut *const CFData, ) -> i32

Available on crate features CFData and CFDate only.

Safety

• data might not allow None.
• reply_mode might not allow None.
• return_data must be a valid pointer.

pub fn new_run_loop_source( allocator: Option<&CFAllocator>, local: Option<&CFMessagePort>, order: CFIndex, ) -> Option<CFRetained<CFRunLoopSource>>

Available on crate feature CFRunLoop only.

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

Available on crate feature dispatch2 only.

Safety

• queue possibly has additional threading requirements.
• queue might not allow None.

Methods from Deref<Target = CFType>

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

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 CFMessagePort

fn as_ref(&self) -> &AnyObject

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

impl AsRef<CFMessagePort> for CFMessagePort

fn as_ref(&self) -> &Self

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

impl AsRef<CFType> for CFMessagePort

fn as_ref(&self) -> &CFType

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

impl Borrow<AnyObject> for CFMessagePort

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CFMessagePort

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CFMessagePort

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CFMessagePort

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

Formats the value using the given formatter.

impl Deref for CFMessagePort

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for CFMessagePort

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 CFMessagePort

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CFMessagePort

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 CFMessagePort

const ENCODING_REF: Encoding

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

impl Type for CFMessagePort

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

where Self: Sized,

Increment the reference count of the receiver.
