Struct CFBag 

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

Safe wrapper around a retained Core Foundation CFBag reference.

Implementations

impl CFBag

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

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

Safety

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

Safety

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

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased CFType.

impl CFBag

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

Create a bag from borrowed Core Foundation values.

pub fn len(&self) -> usize

Number of values in the bag.

pub fn is_empty(&self) -> bool

Whether the bag is empty.

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

Whether the bag contains candidate.

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

Number of times candidate appears in the bag.
