Struct CFFileDescriptor 

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

Safe wrapper around a retained Core Foundation CFFileDescriptor reference.

Implementations

impl CFFileDescriptor

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

Wraps a +1 retained CFFileDescriptor pointer and returns None for null.

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

Retains a +0 borrowed CFFileDescriptor pointer and wraps the resulting +1 reference.

Safety

ptr must be NULL or a valid CFFileDescriptor pointer.

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

Returns the wrapped raw Core Foundation pointer.

pub fn type_id() -> usize

Returns the Core Foundation type ID for CFFileDescriptor.

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased CFType.

impl CFFileDescriptor

pub fn from_raw_fd(native_fd: i32, close_on_invalidate: bool) -> Option<Self>

Wrap a native file descriptor with a no-op callback.

pub fn native_descriptor(&self) -> i32

Underlying native file descriptor.

pub fn invalidate(&self)

Invalidate the descriptor.

Trait Implementations

impl AsCFType for CFFileDescriptor

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 CFFileDescriptor

fn clone(&self) -> CFFileDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CFFileDescriptor

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

Formats the value using the given formatter.

impl Hash for CFFileDescriptor

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 PartialEq for CFFileDescriptor

fn eq(&self, other: &CFFileDescriptor) -> 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.
