Methods from Deref<Target = CFType>

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

where T: ConcreteType,

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

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

impl AsRef<CFType> for CGPath

fn as_ref(&self) -> &CFType

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

impl AsRef<CGPath> for CGMutablePath

fn as_ref(&self) -> &CGPath

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

impl AsRef<CGPath> for CGPath

fn as_ref(&self) -> &Self

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

impl Borrow<AnyObject> for CGPath

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CGPath

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl Borrow<CGPath> for CGMutablePath

fn borrow(&self) -> &CGPath

Immutably borrows from an owned value.

impl ConcreteType for CGPath

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CGPath

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

Formats the value using the given formatter.

impl Deref for CGPath

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for CGPath

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

impl Message for CGPath

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CGPath

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 Type for CGPath

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

where Self: Sized,
