Struct core_graphics::display::CFArray

pub struct CFArray<T = *const c_void>(/* private fields */);

A heterogeneous immutable array.

Implementations

impl<T> CFArray<T>

pub fn from_copyable(elems: &[T]) -> CFArray<T>

where T: Copy,

Creates a new CFArray with the given elements, which must implement Copy.

pub fn from_CFTypes(elems: &[T]) -> CFArray<T>

where T: TCFType,

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

pub fn to_untyped(&self) -> CFArray

pub fn into_untyped(self) -> CFArray

Returns the same array, but with the type reset to void pointers. Equal to to_untyped, but is faster since it does not increment the retain count.

pub fn iter(&self) -> CFArrayIterator<'_, T>

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().

pub fn len(&self) -> isize

pub fn is_empty(&self) -> bool

Returns true if the array contains no elements.

pub unsafe fn get_unchecked(&self, index: isize) -> ItemRef<'_, T>

where T: FromVoid,

pub fn get(&self, index: isize) -> Option<ItemRef<'_, T>>

where T: FromVoid,

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

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

Trait Implementations

impl CFPropertyListSubClass for CFArray

fn to_CFPropertyList(&self) -> CFPropertyList

Create an instance of the superclass type CFPropertyList for this instance.

fn into_CFPropertyList(self) -> CFPropertyList

where Self: Sized,

Equal to to_CFPropertyList, but consumes self and avoids changing the reference count.

impl Clone for CFArray

fn clone(&self) -> CFArray

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for CFArray<T>

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

Formats the value using the given formatter.

impl<T> Drop for CFArray<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, T> IntoIterator for &'a CFArray<T>

where T: FromVoid,

type Item = ItemRef<'a, T>

The type of the elements being iterated over.

type IntoIter = CFArrayIterator<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> CFArrayIterator<'a, T>

Creates an iterator from a value.

impl PartialEq for CFArray

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

impl<T> TCFType for CFArray<T>

type Ref = *const __CFArray

The reference type wrapped inside this type.

fn as_concrete_TypeRef(&self) -> *const __CFArray

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: *const __CFArray) -> CFArray<T>

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) -> *const c_void

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

unsafe fn wrap_under_create_rule(reference: *const __CFArray) -> CFArray<T>

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() -> usize

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 into_CFType(self) -> CFType

where Self: Sized,

Returns the object as a wrapped CFType. Consumes self and avoids changing the reference count.

fn retain_count(&self) -> isize

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) -> usize

Returns the type ID of this object.

fn show(&self)

Writes a debugging version of this object on standard error.

fn instance_of<OtherCFType>(&self) -> bool

where OtherCFType: TCFType,

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