Struct CFMutableSet 

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

Implementations

impl CFMutableSet

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 CFMutableSet

pub fn new() -> Self

Create an empty mutable set using Core Foundation type callbacks.

pub fn with_callbacks(capacity: usize, callbacks: CFSetCallbacks) -> Self

Create an empty mutable set with explicit callback semantics.

pub fn from_values(values: &[&dyn AsCFType]) -> Self

Create a mutable set from borrowed Core Foundation values using type callbacks.

pub fn from_values_with_callbacks( values: &[&dyn AsCFType], callbacks: CFSetCallbacks, ) -> Self

Create a mutable set from borrowed Core Foundation values with explicit callback semantics.

pub fn copy(&self) -> CFSet

Create an immutable retained copy of this set.

pub fn mutable_copy(&self, capacity: usize) -> Self

Create a mutable retained copy of this set.

pub fn len(&self) -> usize

Number of values in the set.

pub fn is_empty(&self) -> bool

Whether the set is empty.

pub fn contains(&self, candidate: &dyn AsCFType) -> bool

Whether the set contains candidate.

pub fn count_of_value(&self, candidate: &dyn AsCFType) -> usize

Number of times candidate appears in the set (0 or 1).

pub fn values(&self) -> Vec<CFType>

Copy all values into a Rust vector.

pub fn add(&self, candidate: &dyn AsCFType)

Add candidate if it is not already present.

pub fn replace(&self, candidate: &dyn AsCFType)

Replace the matching value if it is already present.

pub fn set(&self, candidate: &dyn AsCFType)

Insert or replace candidate.

pub fn remove(&self, candidate: &dyn AsCFType)

Remove candidate if it exists.

pub fn clear(&self)

Remove every value from the set.

pub fn for_each<F>(&self, callback: F)

where F: FnMut(CFType),

Call callback once for each value in the set.

Trait Implementations

impl AsCFType for CFMutableSet

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 CFMutableSet

fn clone(&self) -> CFMutableSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CFMutableSet

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

Formats the value using the given formatter.

impl Default for CFMutableSet

fn default() -> Self

Returns the “default value” for a type.

impl Hash for CFMutableSet

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 CFMutableSet

fn eq(&self, other: &CFMutableSet) -> 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.
