Implementations
Trait Implementations
sourceimpl CFPropertyListSubClass for CFNumber
impl CFPropertyListSubClass for CFNumber
sourcefn to_CFPropertyList(&self) -> CFPropertyList
fn to_CFPropertyList(&self) -> CFPropertyList
Create an instance of the superclass type CFPropertyList
for this instance. Read more
sourcefn into_CFPropertyList(self) -> CFPropertyList where
Self: Sized,
fn into_CFPropertyList(self) -> CFPropertyList where
Self: Sized,
Equal to to_CFPropertyList
, but consumes self and avoids changing the reference count. Read more
sourceimpl Ord for CFNumber
impl Ord for CFNumber
sourceimpl PartialOrd<CFNumber> for CFNumber
impl PartialOrd<CFNumber> for CFNumber
sourcefn partial_cmp(&self, other: &CFNumber) -> Option<Ordering>
fn partial_cmp(&self, other: &CFNumber) -> Option<Ordering>
This method returns an ordering between self
and other
values if one exists. Read more
1.0.0 · sourcefn lt(&self, other: &Rhs) -> bool
fn lt(&self, other: &Rhs) -> bool
This method tests less than (for self
and other
) and is used by the <
operator. Read more
1.0.0 · sourcefn le(&self, other: &Rhs) -> bool
fn le(&self, other: &Rhs) -> bool
This method tests less than or equal to (for self
and other
) and is used by the <=
operator. Read more
sourceimpl TCFType for CFNumber
impl TCFType for CFNumber
type Ref = CFNumberRef
type Ref = CFNumberRef
The reference type wrapped inside this type.
sourcefn as_concrete_TypeRef(&self) -> CFNumberRef
fn as_concrete_TypeRef(&self) -> CFNumberRef
Returns the object as its concrete TypeRef.
sourceunsafe fn wrap_under_get_rule(reference: CFNumberRef) -> Self
unsafe fn wrap_under_get_rule(reference: CFNumberRef) -> 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: CFNumberRef) -> Self
unsafe fn wrap_under_create_rule(reference: CFNumberRef) -> 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.
