Implementations

impl<T: ?Sized> CFBag<T>

pub unsafe fn cast_unchecked<NewT: ?Sized>(&self) -> &CFBag<NewT>

Unchecked conversion of the generic parameter.

Safety

The generic must be valid to reinterpret as the given type.

pub fn as_opaque(&self) -> &CFBag

Convert to the opaque/untyped variant.

impl CFBag

pub unsafe fn new( allocator: Option<&CFAllocator>, values: *mut *const c_void, num_values: CFIndex, call_backs: *const CFBagCallBacks, ) -> Option<CFRetained<CFBag>>

Safety

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

pub unsafe fn new_copy( allocator: Option<&CFAllocator>, the_bag: Option<&CFBag>, ) -> Option<CFRetained<CFBag>>

Safety

• allocator might not allow None.
• the_bag generic must be of the correct type.
• the_bag might not allow None.

impl CFBag

pub unsafe fn count(&self) -> CFIndex

Safety

the_bag generic must be of the correct type.

pub unsafe fn count_of_value(&self, value: *const c_void) -> CFIndex

Safety

• the_bag generic must be of the correct type.
• value must be a valid pointer.

pub unsafe fn contains_value(&self, value: *const c_void) -> bool

Safety

• the_bag generic must be of the correct type.
• value must be a valid pointer.

pub unsafe fn value(&self, value: *const c_void) -> *const c_void

Safety

• the_bag generic must be of the correct type.
• value must be a valid pointer.

pub unsafe fn value_if_present( &self, candidate: *const c_void, value: *mut *const c_void, ) -> bool

Safety

• the_bag generic must be of the correct type.
• candidate must be a valid pointer.
• value must be a valid pointer.

pub unsafe fn values(&self, values: *mut *const c_void)

Safety

• the_bag generic must be of the correct type.
• values must be a valid pointer.

pub unsafe fn apply_function( &self, applier: CFBagApplierFunction, context: *mut c_void, )

Safety

• the_bag generic must be of the correct type.
• applier must be implemented correctly.
• 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.

Formats the value using the given formatter.

impl<T: ?Sized> Deref for CFBag<T>

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl<T: ?Sized> Hash for CFBag<T>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

impl<T: ?Sized> Message for CFBag<T>

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

where Self: Sized,

Increment the reference count of the receiver.
