Struct CFDictionary 

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

Implementations

impl CFDictionary

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

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

Retain a borrowed pointer before wrapping it.

Safety

ptr must be NULL or a valid pointer of the expected Core Foundation type.

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

pub fn type_id() -> usize

pub fn into_cf_type(self) -> 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.

Trait Implementations

impl AsCFType for CFDictionary

fn as_ptr(&self) -> *mut c_void

Borrow the underlying Core Foundation object pointer.

fn to_cf_type(&self) -> CFType

Clone this value as an erased CFType.

impl Clone for CFDictionary

fn clone(&self) -> CFDictionary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CFDictionary

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

Formats the value using the given formatter.

impl Hash for CFDictionary

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
