impl Drop for CFNumber[src]
impl Drop for CFNumberimpl TCFType<CFNumberRef> for CFNumber[src]
impl TCFType<CFNumberRef> for CFNumberfn as_concrete_TypeRef(&self) -> CFNumberRef[src]
fn as_concrete_TypeRef(&self) -> CFNumberRefReturns the object as its concrete TypeRef.
unsafe fn wrap_under_get_rule(reference: CFNumberRef) -> CFNumber[src]
unsafe fn wrap_under_get_rule(reference: CFNumberRef) -> CFNumberReturns an instance of the object, wrapping the underlying CFTypeRef subclass. Use this when following Core Foundation's "Get Rule". The reference count is bumped. Read more
fn as_CFTypeRef(&self) -> CFTypeRef[src]
fn as_CFTypeRef(&self) -> CFTypeRefReturns the object as a raw CFTypeRef. The reference count is not adjusted.
unsafe fn wrap_under_create_rule(obj: CFNumberRef) -> CFNumber[src]
unsafe fn wrap_under_create_rule(obj: CFNumberRef) -> CFNumberReturns 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. Read more
fn type_id() -> CFTypeID[src]
fn type_id() -> CFTypeIDReturns the type ID for this class.
fn as_CFType(&self) -> CFType[src]
fn as_CFType(&self) -> CFTypeReturns the object as a wrapped CFType. The reference count is incremented by one.
fn retain_count(&self) -> CFIndex[src]
fn retain_count(&self) -> CFIndexReturns 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. Read more
fn type_of(&self) -> CFTypeID[src]
fn type_of(&self) -> CFTypeIDReturns the type ID of this object.
fn show(&self)[src]
fn show(&self)Writes a debugging version of this object on standard error.
fn instance_of<OtherConcreteTypeRef, OtherCFType: TCFType<OtherConcreteTypeRef>>(
&self
) -> bool[src]
fn instance_of<OtherConcreteTypeRef, OtherCFType: TCFType<OtherConcreteTypeRef>>(
&self
) -> boolReturns true if this value is an instance of another type.
