Source§fn as_concrete_TypeRef(&self) -> CGLayerRef
fn as_concrete_TypeRef(&self) -> CGLayerRef
Returns the object as its concrete
TypeRef
.Source§unsafe fn wrap_under_get_rule(reference: CGLayerRef) -> Self
unsafe fn wrap_under_get_rule(reference: CGLayerRef) -> 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.Source§fn as_CFTypeRef(&self) -> CFTypeRef
fn as_CFTypeRef(&self) -> CFTypeRef
Returns the object as a raw
CFTypeRef
. The reference count is not adjusted.Source§unsafe fn wrap_under_create_rule(reference: CGLayerRef) -> Self
unsafe fn wrap_under_create_rule(reference: CGLayerRef) -> 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.Source§fn as_CFType(&self) -> CFType
fn as_CFType(&self) -> CFType
Returns the object as a wrapped
CFType
. The reference count is incremented by one.Source§fn into_CFType(self) -> CFTypewhere
Self: Sized,
fn into_CFType(self) -> CFTypewhere
Self: Sized,
Returns the object as a wrapped
CFType
. Consumes self and avoids changing the reference
count.Source§fn retain_count(&self) -> isize
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.

OtherCFType: TCFType,
fn instance_of<OtherCFType>(&self) -> boolwhere
OtherCFType: TCFType,
Returns
true
if this value is an instance of another type.impl ConcreteCFType for CGLayer
