Struct core_foundation::boolean::CFBoolean

pub struct CFBoolean(_);

A Boolean type.

FIXME(pcwalton): Should be a newtype struct, but that fails due to a Rust compiler bug.

Implementations

impl CFBoolean

pub fn true_value() -> CFBoolean

pub fn false_value() -> CFBoolean

Trait Implementations

impl CFPropertyListSubClass for CFBoolean

fn to_CFPropertyList(&self) -> CFPropertyList

Create an instance of the superclass type CFPropertyList for this instance.

fn into_CFPropertyList(self) -> CFPropertyListwhere
    Self: Sized,

Equal to to_CFPropertyList, but consumes self and avoids changing the reference count.

impl Clone for CFBoolean

fn clone(&self) -> CFBoolean

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CFBoolean

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for CFBoolean

fn drop(&mut self)

Executes the destructor for this type.

impl From<CFBoolean> for bool

fn from(value: CFBoolean) -> bool

Converts to this type from the input type.

impl From<bool> for CFBoolean

fn from(value: bool) -> CFBoolean

Converts to this type from the input type.

impl PartialEq<CFBoolean> for CFBoolean

fn eq(&self, other: &CFBoolean) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TCFType for CFBoolean

type Ref = *const __CFBoolean

The reference type wrapped inside this type.

fn as_concrete_TypeRef(&self) -> CFBooleanRef

Returns the object as its concrete TypeRef.

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.

fn as_CFTypeRef(&self) -> CFTypeRef

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

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.

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 into_CFType(self) -> CFTypewhere
    Self: Sized,

Returns the object as a wrapped CFType. Consumes self and avoids changing the reference count.

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<OtherCFType: TCFType>(&self) -> bool

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