Struct core_foundation::array::CFArray
source · [−]Expand description
A heterogeneous immutable array.
Implementations
sourceimpl<T> CFArray<T>
impl<T> CFArray<T>
sourcepub fn from_copyable(elems: &[T]) -> CFArray<T> where
T: Copy,
pub fn from_copyable(elems: &[T]) -> CFArray<T> where
T: Copy,
Creates a new CFArray with the given elements, which must implement Copy.
sourcepub fn from_CFTypes(elems: &[T]) -> CFArray<T> where
T: TCFType,
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
sourcepub fn into_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.
sourcepub fn iter<'a>(&'a self) -> CFArrayIterator<'a, T>ⓘNotable traits for CFArrayIterator<'a, T>impl<'a, T: FromVoid> Iterator for CFArrayIterator<'a, T> type Item = ItemRef<'a, T>;
pub fn iter<'a>(&'a self) -> CFArrayIterator<'a, T>ⓘNotable traits for CFArrayIterator<'a, T>impl<'a, T: FromVoid> Iterator for CFArrayIterator<'a, T> type Item = ItemRef<'a, 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) -> CFIndex
pub unsafe fn get_unchecked<'a>(&'a self, index: CFIndex) -> ItemRef<'a, T> where
T: FromVoid,
pub fn get<'a>(&'a self, index: CFIndex) -> Option<ItemRef<'a, 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>

impl CFPropertyListSubClass for CFArray
sourcefn to_CFPropertyList(&self) -> CFPropertyList
fn to_CFPropertyList(&self) -> CFPropertyList
Create an instance of the superclass type CFPropertyList for this instance. Read more
sourcefn into_CFPropertyList(self) -> CFPropertyList where
Self: Sized,
fn into_CFPropertyList(self) -> CFPropertyList where
Self: Sized,
Equal to to_CFPropertyList, but consumes self and avoids changing the reference count. Read more

fn into_iter(self) -> CFArrayIterator<'a, T>ⓘNotable traits for CFArrayIterator<'a, T>impl<'a, T: FromVoid> Iterator for CFArrayIterator<'a, T> type Item = ItemRef<'a, T>;

sourceimpl<T> TCFType for CFArray<T>
impl<T> TCFType for CFArray<T>
type Ref = CFArrayRef
type Ref = CFArrayRef
The reference type wrapped inside this type.
sourcefn as_concrete_TypeRef(&self) -> CFArrayRef
fn as_concrete_TypeRef(&self) -> CFArrayRef
Returns the object as its concrete TypeRef.
sourceunsafe fn wrap_under_get_rule(reference: CFArrayRef) -> Self
unsafe fn wrap_under_get_rule(reference: CFArrayRef) -> Self
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. Read more
sourcefn as_CFTypeRef(&self) -> CFTypeRef
fn as_CFTypeRef(&self) -> CFTypeRef
Returns the object as a raw CFTypeRef. The reference count is not adjusted.
sourceunsafe fn wrap_under_create_rule(reference: CFArrayRef) -> Self
unsafe fn wrap_under_create_rule(reference: CFArrayRef) -> Self
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. Read more
sourcefn as_CFType(&self) -> CFType
fn as_CFType(&self) -> CFType
Returns the object as a wrapped CFType. The reference count is incremented by one.
sourcefn into_CFType(self) -> CFType where
Self: Sized,
fn into_CFType(self) -> CFType where
Self: Sized,
Returns the object as a wrapped CFType. Consumes self and avoids changing the reference
count. Read more
sourcefn retain_count(&self) -> CFIndex
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. Read more
sourcefn instance_of<OtherCFType: TCFType>(&self) -> bool
fn instance_of<OtherCFType: TCFType>(&self) -> bool
Returns true if this value is an instance of another type.
