Struct core_foundation::boolean::CFBoolean
source · pub struct CFBoolean(/* private fields */);
Expand description
A Boolean type.
FIXME(pcwalton): Should be a newtype struct, but that fails due to a Rust compiler bug.

Trait Implementations§

impl CFPropertyListSubClass for CFBoolean
source§fn to_CFPropertyList(&self) -> CFPropertyList
fn to_CFPropertyList(&self) -> CFPropertyList
Create an instance of the superclass type
CFPropertyList
for this instance.source§fn into_CFPropertyList(self) -> CFPropertyListwhere
Self: Sized,
fn into_CFPropertyList(self) -> CFPropertyListwhere
Self: Sized,
Equal to
to_CFPropertyList
, but consumes self and avoids changing the reference count.source§impl TCFType for CFBoolean
impl TCFType for CFBoolean
§type Ref = *const __CFBoolean
type Ref = *const __CFBoolean
The reference type wrapped inside this type.
source§fn as_concrete_TypeRef(&self) -> CFBooleanRef
fn as_concrete_TypeRef(&self) -> CFBooleanRef
Returns the object as its concrete
TypeRef
.source§unsafe fn wrap_under_get_rule(reference: CFBooleanRef) -> Self
unsafe fn wrap_under_get_rule(reference: CFBooleanRef) -> 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: CFBooleanRef) -> Self
unsafe fn wrap_under_create_rule(reference: CFBooleanRef) -> 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) -> 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.
source§fn instance_of<OtherCFType: TCFType>(&self) -> bool
fn instance_of<OtherCFType: TCFType>(&self) -> bool
Returns
true
if this value is an instance of another type.impl ConcreteCFType for CFBoolean
