Struct CFSet 

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

Safe wrapper around a retained Core Foundation CFSet reference.

Implementations

impl CFSet

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

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

Safety

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

Safety

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

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased CFType.

impl CFSet

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

Create an immutable set from borrowed Core Foundation values using type callbacks.

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

Create an immutable set from borrowed Core Foundation values with explicit callback semantics.

pub fn copy(&self) -> Self

Create an immutable retained copy of this set.

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

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 get(&self, candidate: &dyn AsCFType) -> Option<CFType>

Copy a matching value using CFSetGetValue semantics.

pub fn get_if_present(&self, candidate: &dyn AsCFType) -> Option<CFType>

Copy a matching value using CFSetGetValueIfPresent semantics.

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

Copy all values into a Rust vector.

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

where F: FnMut(CFType),

Call callback once for each value in the set.

Trait Implementations
