sourceimpl Error for CFError
impl Error for CFError
sourcefn description(&self) -> &str
fn description(&self) -> &str
use the Display impl or to_string()
1.30.0 · sourcefn source(&self) -> Option<&(dyn Error + 'static)>
fn source(&self) -> Option<&(dyn Error + 'static)>
The lower-level source of this error, if any. Read more
sourceimpl TCFType for CFError
impl TCFType for CFError
type Ref = CFErrorRef
type Ref = CFErrorRef
The reference type wrapped inside this type.
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 more
sourcefn 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 more
sourcefn 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) -> CFType where
Self: Sized,
fn into_CFType(self) -> CFType where
Self: Sized,
Returns the object as a wrapped CFType
. Consumes self and avoids changing the reference
count. Read more
sourcefn 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.
