Implementations§

source§

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

source

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

source

pub fn to_untyped(&self) -> CFDictionary

source

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.

source

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.

source

pub fn len(&self) -> usize

source

pub fn is_empty(&self) -> bool

source

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

source

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

source

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

source

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

Trait Implementations§

impl CFPropertyListSubClass for CFDictionary

source§

fn to_CFPropertyList(&self) -> CFPropertyList

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

fn into_CFPropertyList(self) -> CFPropertyList
where Self: Sized,

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

source§

impl<'a, K, V> From<&'a CFDictionary<K, V>> for CFMutableDictionary<K, V>

source§

fn from(dict: &'a CFDictionary<K, V>) -> Self

Creates a new mutable dictionary with the key-value pairs from another dictionary. The capacity of the new mutable dictionary is not limited.

source§

impl PartialEq for CFDictionary

source§

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

Tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

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

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

§

type Ref = *const __CFDictionary

The reference type wrapped inside this type.
source§

fn as_concrete_TypeRef(&self) -> CFDictionaryRef

Returns the object as its concrete TypeRef.
source§

unsafe fn wrap_under_get_rule(reference: CFDictionaryRef) -> 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

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

unsafe fn wrap_under_create_rule(reference: CFDictionaryRef) -> 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 type_id() -> CFTypeID

Returns the type ID for this class.
source§

fn as_CFType(&self) -> CFType

Returns the object as a wrapped CFType. The reference count is incremented by one.
source§

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

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

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 type_of(&self) -> CFTypeID

Returns the type ID of this object.
source§

fn show(&self)

Writes a debugging version of this object on standard error.
source§

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

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