#[repr(C)]
pub struct SCPreferences { /* private fields */ }

Available on crate feature SCPreferences only.

This is the handle to an open preferences session for accessing system configuration preferences.

Methods from Deref<Target = CFType>

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

where T: ConcreteType,

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.

Trait Implementations

impl AsRef<AnyObject> for SCPreferences

fn as_ref(&self) -> &AnyObject

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

impl AsRef<CFType> for SCPreferences

fn as_ref(&self) -> &CFType

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

impl AsRef<SCPreferences> for SCPreferences

fn as_ref(&self) -> &Self

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

impl Borrow<AnyObject> for SCPreferences

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for SCPreferences

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for SCPreferences

fn type_id() -> CFTypeID

Returns the type identifier of all SCPreferences instances.

impl Debug for SCPreferences

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

Formats the value using the given formatter.

impl Deref for SCPreferences

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for SCPreferences

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for SCPreferences

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for SCPreferences

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 SCPreferences

const ENCODING_REF: Encoding

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

impl Type for SCPreferences

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

where Self: Sized,

Increment the reference count of the receiver.
