Methods from Deref<Target = CGPath>

pub unsafe fn apply_with_block(&self, block: CGPathApplyBlock)

Available on crate feature block2 only.

Safety

block must be a valid pointer.

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<CGMutablePath> for CGMutablePath

fn as_ref(&self) -> &Self

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 Borrow<AnyObject> for CGMutablePath

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CGMutablePath

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 Debug for CGMutablePath

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

Formats the value using the given formatter.

impl Deref for CGMutablePath

type Target = CGPath

The resulting type after dereferencing.

impl Message for CGMutablePath

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

where Self: Sized,
