Implementations

impl CGImageDestination

pub unsafe fn type_identifiers() -> CFRetained<CFArray>

pub unsafe fn with_data_consumer( consumer: &CGDataConsumer, type: &CFString, count: usize, options: Option<&CFDictionary>, ) -> Option<CFRetained<CGImageDestination>>

Available on crate feature objc2-core-graphics only.

Safety

options generics must be of the correct type.

pub unsafe fn with_data( data: &CFMutableData, type: &CFString, count: usize, options: Option<&CFDictionary>, ) -> Option<CFRetained<CGImageDestination>>

Safety

options generics must be of the correct type.

pub unsafe fn with_url( url: &CFURL, type: &CFString, count: usize, options: Option<&CFDictionary>, ) -> Option<CFRetained<CGImageDestination>>

Safety

options generics must be of the correct type.

pub unsafe fn set_properties(&self, properties: Option<&CFDictionary>)

Safety

properties generics must be of the correct type.

pub unsafe fn add_image( &self, image: &CGImage, properties: Option<&CFDictionary>, )

Available on crate feature objc2-core-graphics only.

Safety

properties generics must be of the correct type.

pub unsafe fn add_image_from_source( &self, isrc: &CGImageSource, index: usize, properties: Option<&CFDictionary>, )

Available on crate feature CGImageSource only.

Safety

properties generics must be of the correct type.

pub unsafe fn finalize(&self) -> bool

pub unsafe fn add_image_and_metadata( &self, image: &CGImage, metadata: Option<&CGImageMetadata>, options: Option<&CFDictionary>, )

Available on crate features CGImageMetadata and objc2-core-graphics only.

Safety

options generics must be of the correct type.

impl CGImageDestination

pub unsafe fn copy_image_source( &self, isrc: &CGImageSource, options: Option<&CFDictionary>, err: *mut *mut CFError, ) -> bool

Available on crate feature CGImageSource only.

Safety

• options generics must be of the correct type.
• err must be a valid pointer or null.

pub unsafe fn add_auxiliary_data_info( &self, auxiliary_image_data_type: &CFString, auxiliary_data_info_dictionary: &CFDictionary, )

Safety

auxiliary_data_info_dictionary generics must be of the correct type.

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

impl AsRef<AnyObject> for CGImageDestination

fn as_ref(&self) -> &AnyObject

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

impl AsRef<CFType> for CGImageDestination

fn as_ref(&self) -> &CFType

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

impl AsRef<CGImageDestination> for CGImageDestination

fn as_ref(&self) -> &Self

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

impl Borrow<AnyObject> for CGImageDestination

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CGImageDestination

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CGImageDestination

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CGImageDestination

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

Formats the value using the given formatter.

impl Deref for CGImageDestination

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for CGImageDestination

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 Message for CGImageDestination

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CGImageDestination

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 RefEncode for CGImageDestination

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Type for CGImageDestination

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

where Self: Sized,

Increment the reference count of the receiver.

unsafe fn wrap_under_create_rule(ptr: *const Self) -> CFRetained<Self>

where Self: Sized,

👎Deprecated: use CFRetained::from_raw
