Struct CFMutableSet 

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

Safe wrapper around a retained Core Foundation CFMutableSet reference.

Implementations

impl CFMutableSet

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

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

Safety

A non-null ptr must be a live CFMutableSet 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 CFMutableSet pointer and returns an owned wrapper.

Safety

A non-null ptr must be a live CFMutableSet 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 CFMutableSet.

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased 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.
