Implementations

impl CFURLEnumerator

pub unsafe fn new_for_directory_url( alloc: Option<&CFAllocator>, directory_url: Option<&CFURL>, option: CFURLEnumeratorOptions, property_keys: Option<&CFArray>, ) -> Option<CFRetained<CFURLEnumerator>>

Available on crate features CFArray and CFURL only.

Safety

• alloc might not allow None.
• directory_url might not allow None.
• property_keys generic must be of the correct type.
• property_keys might not allow None.

pub unsafe fn new_for_mounted_volumes( alloc: Option<&CFAllocator>, option: CFURLEnumeratorOptions, property_keys: Option<&CFArray>, ) -> Option<CFRetained<CFURLEnumerator>>

Available on crate feature CFArray only.

Safety

• alloc might not allow None.
• property_keys generic must be of the correct type.
• property_keys might not allow None.

impl CFURLEnumerator

pub unsafe fn next_url( &self, url: *mut *const CFURL, error: *mut *mut CFError, ) -> CFURLEnumeratorResult

Available on crate features CFError and CFURL only.

Safety

• url must be a valid pointer.
• error must be a valid pointer.

pub fn skip_descendents(&self)

pub fn descendent_level(&self) -> CFIndex

pub fn source_did_change(&self) -> bool

👎Deprecated: Use File System Events API instead

Methods from Deref<Target = CFType>

pub fn downcast_ref<T: ConcreteType>(&self) -> Option<&T>

Attempt to downcast the type to that of type T.

This is the reference-variant. Use CFRetained::downcast if you want to convert a retained type. See also ConcreteType for more details on which types support being converted to.

pub fn retain_count(&self) -> usize

Get the reference count of the object.

This function may be useful for debugging. You normally do not use this function otherwise.

Beware that some things (like CFNumbers, small CFStrings etc.) may not have a normal retain count for optimization purposes, and can return usize::MAX in that case.

impl AsRef<AnyObject> for CFURLEnumerator

fn as_ref(&self) -> &AnyObject

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<CFType> for CFURLEnumerator

fn as_ref(&self) -> &CFType

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<CFURLEnumerator> for CFURLEnumerator

fn as_ref(&self) -> &Self

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<AnyObject> for CFURLEnumerator

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CFURLEnumerator

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CFURLEnumerator

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CFURLEnumerator

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

Formats the value using the given formatter.

impl Deref for CFURLEnumerator

type Target = CFType

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for CFURLEnumerator

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

Feeds a slice of this type into the given Hasher.

impl Message for CFURLEnumerator

fn retain(&self) -> Retained<Self>

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CFURLEnumerator

fn eq(&self, other: &Self) -> 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 RefEncode for CFURLEnumerator

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Type for CFURLEnumerator

fn retain(&self) -> CFRetained<Self>

where Self: Sized,

Increment the reference count of the receiver.

unsafe fn wrap_under_create_rule(ptr: *const Self) -> CFRetained<Self>

where Self: Sized,

👎Deprecated: use CFRetained::from_raw
