pub trait TCFType<ConcreteTypeRef> { fn as_concrete_TypeRef(&self) -> ConcreteTypeRef; unsafe fn wrap_under_create_rule(obj: ConcreteTypeRef) -> Self; fn type_id() -> CFTypeID; fn as_CFTypeRef(&self) -> CFTypeRef; unsafe fn wrap_under_get_rule(reference: ConcreteTypeRef) -> Self; fn as_CFType(&self) -> CFType { ... } fn retain_count(&self) -> CFIndex { ... } fn type_of(&self) -> CFTypeID { ... } fn show(&self) { ... } fn instance_of<OtherConcreteTypeRef, OtherCFType: TCFType<OtherConcreteTypeRef>>(&self)

All Core Foundation types implement this trait. The type parameter TypeRef
specifies the
associated Core Foundation type: e.g. for CFType
this is CFTypeRef
; for CFArray
this is
CFArrayRef
.
Required Methods
fn as_concrete_TypeRef(&self) -> ConcreteTypeRef
Returns the object as its concrete TypeRef.
unsafe fn wrap_under_create_rule(obj: ConcreteTypeRef) -> 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() -> CFTypeID
Returns the type ID for this class.
fn as_CFTypeRef(&self) -> CFTypeRef
Returns the object as a raw CFTypeRef
. The reference count is not adjusted.
unsafe fn wrap_under_get_rule(reference: ConcreteTypeRef) -> 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 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
-> bool
Returns true if this value is an instance of another type.
