Struct core_foundation::array::CFArray

pub struct CFArray(_);

A heterogeneous immutable array.

Methods

impl CFArray

fn from_CFTypes<R, T>(elems: &[T]) -> CFArray where T: TCFType<R>

Creates a new CFArray with the given elements, which must be CFType objects.

fn iter<'a>(&'a self) -> CFArrayIterator<'a>

Iterates over the elements of this CFArray.

Careful; the loop body must wrap the reference properly. Generally, when array elements are Core Foundation objects (not always true), they need to be wrapped with TCFType::wrap_under_get_rule().

fn len(&self) -> CFIndex

fn get(&self, index: CFIndex) -> *const c_void

fn get_values(&self, range: CFRange) -> Vec<*const c_void>

fn get_all_values(&self) -> Vec<*const c_void>

Trait Implementations

impl Drop for CFArray

fn drop(&mut self)

A method called when the value goes out of scope.

impl TCFType<CFArrayRef> for CFArray

fn as_concrete_TypeRef(&self) -> CFArrayRef

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: CFArrayRef) -> CFArray

Returns an instance of the object, wrapping the underlying CFTypeRef subclass. Use this when following Core Foundation's "Get Rule". The reference count is bumped.

fn as_CFTypeRef(&self) -> CFTypeRef

Returns the object as a raw CFTypeRef. The reference count is not adjusted.

unsafe fn wrap_under_create_rule(obj: CFArrayRef) -> CFArray

Returns an instance of the object, wrapping the underlying CFTypeRef subclass. Use this when following Core Foundation's "Create Rule". The reference count is not bumped.

fn type_id() -> CFTypeID

Returns the type ID for this class.

fn as_CFType(&self) -> CFType

Returns the object as a wrapped CFType. The reference count is incremented by one.

fn retain_count(&self) -> CFIndex

Returns the reference count of the object. It is unwise to do anything other than test whether the return value of this method is greater than zero.

fn type_of(&self) -> CFTypeID

Returns the type ID of this object.

fn show(&self)

Writes a debugging version of this object on standard error.

fn instance_of<OtherConcreteTypeRef, OtherCFType: TCFType<OtherConcreteTypeRef>>(&self)
                                                                                 -> bool

Returns true if this value is an instance of another type.

impl<'a> IntoIterator for &'a CFArray

type Item = *const c_void

The type of the elements being iterated over.

type IntoIter = CFArrayIterator<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> CFArrayIterator<'a>

Creates an iterator from a value.
