Struct CFDictionary 

pub struct CFDictionary(/* private fields */);

Safe wrapper around a retained Core Foundation CFDictionary reference.

Implementations

impl CFDictionary

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

Adopts a +1 retained CFDictionary pointer and returns None for null.

Safety

A non-null ptr must be a live CFDictionary pointer of the exact dynamic type carrying one retain transferred to this wrapper. The caller must not release or separately adopt that transferred retain.

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

Retains a +0 borrowed CFDictionary pointer and returns an owned wrapper.

Safety

A non-null ptr must be a live CFDictionary pointer of the exact dynamic type for the duration of the retain call.

pub const fn as_ptr(&self) -> *mut c_void

Borrows the raw +0 Core Foundation pointer while self remains alive.

pub fn type_id() -> usize

Returns the Core Foundation type ID for CFDictionary.

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased CFType.

impl CFDictionary

pub fn from_pairs(pairs: &[(&dyn AsCFType, &dyn AsCFType)]) -> Self

Create a dictionary from borrowed key/value pairs.

pub fn len(&self) -> usize

Number of key/value pairs.

pub fn is_empty(&self) -> bool

Whether the dictionary is empty.

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

Whether key exists in the dictionary.

pub fn get(&self, key: &dyn AsCFType) -> Option<CFType>

Copy the value associated with key.

pub fn keys(&self) -> CFArray

Copy all keys into a CFArray.

pub fn values(&self) -> CFArray

Copy all values into a CFArray.
