impl TCFType for CFError
sourcefn as_concrete_TypeRef(&self) -> CFErrorRef
fn as_concrete_TypeRef(&self) -> CFErrorRef
Returns the object as its concrete TypeRef.
sourceunsafe fn wrap_under_get_rule(reference: CFErrorRef) -> Self
unsafe fn wrap_under_get_rule(reference: CFErrorRef) -> 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. Read moresourcefn as_CFTypeRef(&self) -> CFTypeRef
fn as_CFTypeRef(&self) -> CFTypeRef
Returns the object as a raw
CFTypeRef
. The reference count is not adjusted.sourceunsafe fn wrap_under_create_rule(reference: CFErrorRef) -> Self
unsafe fn wrap_under_create_rule(reference: CFErrorRef) -> 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. Read moresourcefn as_CFType(&self) -> CFType
fn as_CFType(&self) -> CFType
Returns the object as a wrapped
CFType
. The reference count is incremented by one.sourcefn 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. Read moresourcefn retain_count(&self) -> CFIndex
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. Read more
sourcefn instance_of<OtherCFType: TCFType>(&self) -> bool
fn instance_of<OtherCFType: TCFType>(&self) -> bool
Returns true if this value is an instance of another type.
