Methods

impl CFError

fn domain(&self) -> CFString

Returns a string identifying the domain with which this error is associated.

fn code(&self) -> CFIndex

Returns the code identifying this type of error.

fn description(&self) -> CFString

Returns a human-presentable description of the error.

Trait Implementations

impl Drop for CFError

fn drop(&mut self)

A method called when the value goes out of scope.

impl TCFType<CFErrorRef> for CFError

fn as_concrete_TypeRef(&self) -> CFErrorRef

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: CFErrorRef) -> CFError

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.

fn as_CFTypeRef(&self) -> CFTypeRef

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

unsafe fn wrap_under_create_rule(obj: CFErrorRef) -> CFError

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_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

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

impl Debug for CFError

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Display for CFError

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for CFError

fn description(&self) -> &str

A short description of the error.

fn cause(&self) -> Option<&Error>

The lower-level cause of this error, if any.
