Struct Dictionary 

pub struct Dictionary<K = Object, V = Object> { /* private fields */ }

An Objective-C dictionary object.

C++ equivalent: NS::Dictionary

Implementations

impl<K, V> Dictionary<K, V>

pub fn dictionary() -> Option<Self>

Create an empty dictionary.

C++ equivalent: static Dictionary* dictionary()

pub fn dictionary_with_object(object: *const V, key: *const K) -> Option<Self>

Create a dictionary with a single object and key.

C++ equivalent: static Dictionary* dictionary(const Object* pObject, const Object* pKey)

pub fn dictionary_with_objects( objects: *const *const V, keys: *const *const K, count: UInteger, ) -> Option<Self>

Create a dictionary with multiple objects and keys.

C++ equivalent: static Dictionary* dictionary(const Object* const* pObjects, const Object* const* pKeys, UInteger count)

pub fn alloc() -> Option<Self>

Allocate a new dictionary.

C++ equivalent: static Dictionary* alloc()

pub fn init(&self) -> Option<Self>

Initialize an allocated dictionary.

C++ equivalent: Dictionary* init()

pub fn init_with_objects( &self, objects: *const *const V, keys: *const *const K, count: UInteger, ) -> Option<Self>

Initialize with multiple objects and keys.

C++ equivalent: Dictionary* init(const Object* const* pObjects, const Object* const* pKeys, UInteger count)

pub fn init_with_coder(&self, coder: *const c_void) -> Option<Self>

Initialize with a coder.

C++ equivalent: Dictionary* init(const class Coder* pCoder)

pub fn key_enumerator(&self) -> Option<Enumerator<K>>

Get a key enumerator for the dictionary.

C++ equivalent: template <class _KeyType = Object> Enumerator<_KeyType>* keyEnumerator() const

pub fn object(&self, key: *const K) -> *mut V

Get the object for the specified key.

C++ equivalent: template <class _Object = Object> _Object* object(const Object* pKey) const

pub fn count(&self) -> UInteger

Get the count of key-value pairs in the dictionary.

C++ equivalent: UInteger count() const

pub unsafe fn from_ptr(ptr: *mut c_void) -> Option<Self>

Create a Dictionary from a raw pointer.

Safety

The pointer must be a valid Objective-C NSDictionary object.
