Struct CFType 

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

Owned, type-erased CFTypeRef.

Implementations

impl CFType

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

Adopts a +1 retained CFTypeRef and returns None for null.

Safety

A non-null ptr must be a live Core Foundation object pointer carrying one retain that is transferred to the returned 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 CFTypeRef and returns an owned wrapper.

Safety

A non-null ptr must be a live Core Foundation object pointer for the duration of the retain call.

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

Borrow the raw +0 CFTypeRef pointer while self remains alive.

pub fn type_id(&self) -> usize

Runtime type identifier of the wrapped object.

pub fn hash_code(&self) -> usize

CFHash of the wrapped object.

pub fn description(&self) -> String

Human-readable Core Foundation description.

Trait Implementations

impl AsCFType for CFType

fn as_ptr(&self) -> *mut c_void

Borrow the underlying Core Foundation object pointer.

fn to_cf_type(&self) -> CFType

Clone this value as an erased CFType.

impl Clone for CFType

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 CFType

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

Formats the value using the given formatter.

impl Display for CFType

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

Formats the value using the given formatter.

impl Drop for CFType

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
