Trait Implementations

impl Clone for CGDataProvider

fn clone(&self) -> CGDataProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CGDataProvider

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

Formats the value using the given formatter.

impl Drop for CGDataProvider

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq for CGDataProvider

fn eq(&self, other: &CGDataProvider) -> 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 TCFType for CGDataProvider

type Ref = *const __CGDataProvider

The reference type wrapped inside this type.

fn as_concrete_TypeRef(&self) -> CGDataProviderRef

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: CGDataProviderRef) -> Self

Returns an instance of the object, wrapping the underlying CFTypeRef subclass. Use this when following Core Foundation’s “Get Rule”. The reference count is bumped.

fn as_CFTypeRef(&self) -> CFTypeRef

Returns the object as a raw CFTypeRef. The reference count is not adjusted.

unsafe fn wrap_under_create_rule(reference: CGDataProviderRef) -> Self

Returns an instance of the object, wrapping the underlying CFTypeRef subclass. Use this when following Core Foundation’s “Create Rule”. The reference count is not bumped.

fn type_id() -> CFTypeID

Returns the type ID for this class.

fn as_CFType(&self) -> CFType

Returns the object as a wrapped CFType. The reference count is incremented by one.

fn into_CFType(self) -> CFType

where Self: Sized,

Returns the object as a wrapped CFType. Consumes self and avoids changing the reference count.

fn retain_count(&self) -> isize

Returns the reference count of the object. It is unwise to do anything other than test whether the return value of this method is greater than zero.

fn type_of(&self) -> usize

Returns the type ID of this object.

fn show(&self)

Writes a debugging version of this object on standard error.

fn instance_of<OtherCFType>(&self) -> bool

where OtherCFType: TCFType,

Returns true if this value is an instance of another type.
