All Core Foundation types implement this trait. The associated type Ref specifies the associated Core Foundation type: e.g. for CFType this is CFTypeRef; for CFArray this is CFArrayRef.

Most structs that implement this trait will do so via the impl_TCFType macro.

Associated Types

type Ref: TCFTypeRef

The reference type wrapped inside this type.

Required methods

fn as_concrete_TypeRef(&self) -> Self::Ref

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_create_rule(obj: Self::Ref) -> Self

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() -> usize

Returns the type ID for this class.

fn as_CFTypeRef(&self) -> *const c_void

Returns the object as a raw CFTypeRef. The reference count is not adjusted.

unsafe fn wrap_under_get_rule(reference: Self::Ref) -> Self

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.

Provided methods

fn as_CFType(&self) -> CFType

Returns the object as a wrapped CFType. The reference count is incremented by one.

fn into_CFType(self) -> CFType

Returns the object as a wrapped CFType. Consumes self and avoids changing the reference count.

fn retain_count(&self) -> isize

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) -> usize

Returns the type ID of this object.

fn show(&self)

Writes a debugging version of this object on standard error.

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

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