Struct CFReadStream 

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

Safe wrapper around a retained Core Foundation CFReadStream reference.

Implementations

impl CFReadStream

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

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

Safety

A non-null ptr must be a live CFReadStream 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 CFReadStream pointer and returns an owned wrapper.

Safety

A non-null ptr must be a live CFReadStream 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 CFReadStream.

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased CFType.

impl CFReadStream

pub fn open(&self) -> bool

Open the stream.

pub fn close(&self)

Close the stream.

pub fn read(&self, buffer: &mut [u8]) -> Result<usize, isize>

Read bytes into buffer.
