Implementations

impl CFAllocator

pub fn set_default(allocator: Option<&CFAllocator>)

pub fn default() -> Option<CFRetained<CFAllocator>>

pub unsafe fn new( allocator: Option<&CFAllocator>, context: *mut CFAllocatorContext, ) -> Option<CFRetained<CFAllocator>>

Safety

• allocator might not allow None.
• context must be a valid pointer.

pub unsafe fn with_zone( allocator: Option<&CFAllocator>, zone: *mut malloc_zone_t, ) -> Option<CFRetained<CFAllocator>>

Available on crate feature libc only.

Safety

• allocator might not allow None.
• zone must be a valid pointer.

pub unsafe fn allocate_typed( allocator: Option<&CFAllocator>, size: CFIndex, descriptor: CFAllocatorTypeID, hint: CFOptionFlags, ) -> *mut c_void

Safety

allocator might not allow None.

pub unsafe fn reallocate_typed( allocator: Option<&CFAllocator>, ptr: *mut c_void, newsize: CFIndex, descriptor: CFAllocatorTypeID, hint: CFOptionFlags, ) -> *mut c_void

Safety

• allocator might not allow None.
• ptr must be a valid pointer.

pub fn allocate_bytes( allocator: Option<&CFAllocator>, size: CFIndex, hint: CFOptionFlags, ) -> *mut c_void

pub unsafe fn reallocate_bytes( allocator: Option<&CFAllocator>, ptr: *mut c_void, newsize: CFIndex, hint: CFOptionFlags, ) -> *mut c_void

Safety

• allocator might not allow None.
• ptr must be a valid pointer.

pub fn allocate( allocator: Option<&CFAllocator>, size: CFIndex, hint: CFOptionFlags, ) -> *mut c_void

pub unsafe fn reallocate( allocator: Option<&CFAllocator>, ptr: *mut c_void, newsize: CFIndex, hint: CFOptionFlags, ) -> *mut c_void

Safety

• allocator might not allow None.
• ptr must be a valid pointer.

pub unsafe fn deallocate(allocator: Option<&CFAllocator>, ptr: *mut c_void)

Safety

• allocator might not allow None.
• ptr must be a valid pointer.

pub fn preferred_size_for_size( allocator: Option<&CFAllocator>, size: CFIndex, hint: CFOptionFlags, ) -> CFIndex

pub unsafe fn context( allocator: Option<&CFAllocator>, context: *mut CFAllocatorContext, )

Safety

• allocator might not allow None.
• context must be a valid pointer.

Methods from Deref<Target = CFType>

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

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 CFAllocator

fn as_ref(&self) -> &AnyObject

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

impl AsRef<CFAllocator> for CFAllocator

fn as_ref(&self) -> &Self

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

impl AsRef<CFType> for CFAllocator

fn as_ref(&self) -> &CFType

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

impl Borrow<AnyObject> for CFAllocator

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CFAllocator

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CFAllocator

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CFAllocator

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

Formats the value using the given formatter.

impl Deref for CFAllocator

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for CFAllocator

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 CFAllocator

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CFAllocator

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 CFAllocator

const ENCODING_REF: Encoding

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

impl Type for CFAllocator

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>

where Self: Sized,

👎Deprecated:

use CFRetained::retain

Helper for easier transition from the core-foundation crate.

fn as_CFTypeRef(&self) -> &CFType

where Self: AsRef<CFType>,

👎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

Helper for easier transition from the core-foundation crate.
