Methods

fn len(&self) -> usize

fn is_empty(&self) -> bool

fn contains_key(&self, key: *const c_void) -> bool

fn find(&self, key: *const c_void) -> Option<*const c_void>

fn get(&self, key: *const c_void) -> *const c_void

unsafe fn get_CFType(&self, key: *const c_void) -> CFType

A convenience function to retrieve CFType instances.

Trait Implementations

impl Drop for CFDictionary

fn drop(&mut self)

A method called when the value goes out of scope.

impl TCFType<CFDictionaryRef> for CFDictionary

fn as_concrete_TypeRef(&self) -> CFDictionaryRef

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: CFDictionaryRef) -> CFDictionary

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(obj: CFDictionaryRef) -> CFDictionary

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 retain_count(&self) -> CFIndex

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) -> CFTypeID

Returns the type ID of this object.

fn show(&self)

Writes a debugging version of this object on standard error.

fn instance_of<OtherConcreteTypeRef, OtherCFType: TCFType<OtherConcreteTypeRef>>(&self)
                                                                                 -> bool

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