Implementations

impl CGPSConverter

pub unsafe fn new( info: *mut c_void, callbacks: NonNull<CGPSConverterCallbacks>, options: Option<&CFDictionary>, ) -> Option<CFRetained<CGPSConverter>>

Safety

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

pub unsafe fn convert( &self, provider: &CGDataProvider, consumer: &CGDataConsumer, options: Option<&CFDictionary>, ) -> bool

Available on crate features CGDataConsumer and CGDataProvider only.

Safety

options generics must be of the correct type.

pub fn abort(&self) -> bool

pub fn is_converting(&self) -> bool

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 CGPSConverter

fn as_ref(&self) -> &AnyObject

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

impl AsRef<CFType> for CGPSConverter

fn as_ref(&self) -> &CFType

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

impl AsRef<CGPSConverter> for CGPSConverter

fn as_ref(&self) -> &Self

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

impl Borrow<AnyObject> for CGPSConverter

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CGPSConverter

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CGPSConverter

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CGPSConverter

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

Formats the value using the given formatter.

impl Deref for CGPSConverter

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for CGPSConverter

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 CGPSConverter

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CGPSConverter

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 CGPSConverter

const ENCODING_REF: Encoding

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

impl Type for CGPSConverter

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

where Self: Sized,

Increment the reference count of the receiver.

fn as_concrete_TypeRef(&self) -> &Self

👎Deprecated: this is redundant

Helper for easier transition from the core-foundation crate.

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

👎Deprecated: this is redundant (CF types deref to CFType)

Helper for easier transition from the core-foundation crate.

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

where Self: Sized,

👎Deprecated: use CFRetained::from_raw
