Struct core_graphics::display::CFDictionary

pub struct CFDictionary<K = *const c_void, V = *const c_void>(/* private fields */);

Implementations

impl<K, V> CFDictionary<K, V>

pub fn from_CFType_pairs(pairs: &[(K, V)]) -> CFDictionary<K, V>

where K: TCFType, V: TCFType,

pub fn to_untyped(&self) -> CFDictionary

pub unsafe fn to_mutable(&self) -> CFMutableDictionary<K, V>

Returns a CFMutableDictionary pointing to the same underlying dictionary as this immutable one. This should only be used when the underlying dictionary is mutable.

pub fn into_untyped(self) -> CFDictionary

Returns the same dictionary, but with the types reset to void pointers. Equal to to_untyped, but is faster since it does not increment the retain count.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn contains_key(&self, key: &K) -> bool

where K: ToVoid<K>,

pub fn find<T>(&self, key: T) -> Option<ItemRef<'_, V>>

where T: ToVoid<K>, V: FromVoid, K: ToVoid<K>,

pub fn get<T>(&self, key: T) -> ItemRef<'_, V>

where T: ToVoid<K>, V: FromVoid, K: ToVoid<K>,

Panics

Panics if the key is not present in the dictionary. Use find to get an Option instead of panicking.

pub fn get_keys_and_values(&self) -> (Vec<*const c_void>, Vec<*const c_void>)

Trait Implementations

impl CFPropertyListSubClass for CFDictionary

fn to_CFPropertyList(&self) -> CFPropertyList

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

fn into_CFPropertyList(self) -> CFPropertyList

where Self: Sized,

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

impl Clone for CFDictionary

fn clone(&self) -> CFDictionary

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K, V> Debug for CFDictionary<K, V>

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

Formats the value using the given formatter.

impl<K, V> Drop for CFDictionary<K, V>

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq for CFDictionary

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<K, V> TCFType for CFDictionary<K, V>

type Ref = *const __CFDictionary

The reference type wrapped inside this type.

fn as_concrete_TypeRef(&self) -> *const __CFDictionary

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule( reference: *const __CFDictionary, ) -> CFDictionary<K, V>

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) -> *const c_void

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

unsafe fn wrap_under_create_rule( reference: *const __CFDictionary, ) -> CFDictionary<K, V>

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() -> usize

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) -> CFType

where Self: Sized,

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

fn retain_count(&self) -> isize

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) -> usize

Returns the type ID of this object.

fn show(&self)

Writes a debugging version of this object on standard error.

fn instance_of<OtherCFType>(&self) -> bool

where OtherCFType: TCFType,

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