Struct CFMessagePort 

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

Safe wrapper around a retained Core Foundation CFMessagePort reference.

Implementations

impl CFMessagePort

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

Adopts a +1 retained CFMessagePort pointer and returns None for null.

Safety

A non-null ptr must be a live CFMessagePort pointer of the exact dynamic type carrying one retain transferred to this wrapper. The caller must not release or separately adopt that transferred retain.

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

Retains a +0 borrowed CFMessagePort pointer and returns an owned wrapper.

Safety

A non-null ptr must be a live CFMessagePort pointer of the exact dynamic type for the duration of the retain call.

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

Borrows the raw +0 Core Foundation pointer while self remains alive.

pub fn type_id() -> usize

Returns the Core Foundation type ID for CFMessagePort.

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased CFType.

impl CFMessagePort

pub fn create_echo_local(name: &str) -> Self

Create a local message port that echoes request data back as the reply.

pub fn connect_remote(name: &str) -> Option<Self>

Connect to an existing remote message port.

pub fn send_request( &self, bytes: &[u8], timeout: Duration, ) -> Result<Vec<u8>, i32>

Send a request and copy the reply bytes.

pub fn invalidate(&self)

Invalidate the message port.
