Struct core_foundation::propertylist::CFPropertyList

pub struct CFPropertyList(_);

A CFPropertyList struct. This is superclass to CFData, CFString, CFArray, CFDictionary, CFDate, CFBoolean, and CFNumber.

This superclass type does not have its own CFTypeID, instead each instance has the CFTypeID of the subclass it is an instance of. Thus, this type cannot implement the TCFType trait, since it cannot implement the static TCFType::type_id() method.

Methods

impl CFPropertyList

pub fn as_concrete_TypeRef(&self) -> CFPropertyListRef

pub unsafe fn wrap_under_get_rule(
    reference: CFPropertyListRef
) -> CFPropertyList

pub fn as_CFType(&self) -> CFType

pub fn into_CFType(self) -> CFType where
    Self: Sized, 

pub fn as_CFTypeRef(&self) -> CFTypeRef

pub unsafe fn wrap_under_create_rule(obj: CFPropertyListRef) -> CFPropertyList

pub 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.

pub fn type_of(&self) -> CFTypeID

Returns the type ID of this object. Will be one of CFData, CFString, CFArray, CFDictionary, CFDate, CFBoolean, or CFNumber.

pub fn show(&self)

Writes a debugging version of this object on standard error.

pub fn instance_of<OtherCFType: TCFType>(&self) -> bool

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

impl CFPropertyList

pub fn downcast<T: CFPropertyListSubClass>(&self) -> Option<T>

Try to downcast the CFPropertyList to a subclass. Checking if the instance is the correct subclass happens at runtime and None is returned if it is not the correct type. Works similar to Box::downcast and CFType::downcast.

Examples

// Create a string.
let string: CFString = CFString::from_static_string("FooBar");
// Cast it up to a property list.
let propertylist: CFPropertyList = string.to_CFPropertyList();
// Cast it down again.
assert_eq!(propertylist.downcast::<CFString>().unwrap().to_string(), "FooBar");

pub fn downcast_into<T: CFPropertyListSubClass>(self) -> Option<T>

Similar to downcast, but consumes self and can thus avoid touching the retain count.

Trait Implementations

impl Drop for CFPropertyList

fn drop(&mut self)

Executes the destructor for this type.

impl Eq for CFPropertyList

impl PartialEq<CFPropertyList> for CFPropertyList

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

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

#[must_use]

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

This method tests for !=.

impl Clone for CFPropertyList

fn clone(&self) -> CFPropertyList

Returns a copy of the value.

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

Performs copy-assignment from source.
