Struct system_configuration::preferences::SCPreferences

pub struct SCPreferences(_);

The handle to an open preferences session for accessing system configuration preferences.

Implementations

impl SCPreferences

pub fn default(calling_process_name: &CFString) -> Self

Initiates access to the default system preferences using the default allocator.

pub fn group(calling_process_name: &CFString, prefs_id: &CFString) -> Self

Initiates access to the given (prefs_id) group of configuration preferences using the default allocator. To access the default system preferences, use the default constructor.

pub fn new(
    allocator: Option<&CFAllocator>,
    calling_process_name: &CFString,
    prefs_id: Option<&CFString>
) -> Self

Initiates access to the per-system set of configuration preferences with a given allocator and preference group to access. See the underlying SCPreferencesCreate function documentation for details. Use the helper constructors default and group to easier create an instance using the default allocator.

Trait Implementations

impl Clone for SCPreferences

fn clone(&self) -> SCPreferences

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ConcreteCFType for SCPreferences

impl Drop for SCPreferences

fn drop(&mut self)

Executes the destructor for this type.

impl Eq for SCPreferences

impl PartialEq<SCPreferences> for SCPreferences

fn eq(&self, other: &SCPreferences) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl TCFType for SCPreferences

type Ref = SCPreferencesRef

The reference type wrapped inside this type.

fn as_concrete_TypeRef(&self) -> SCPreferencesRef

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: SCPreferencesRef) -> 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.

fn as_CFTypeRef(&self) -> CFTypeRef

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

unsafe fn wrap_under_create_rule(reference: SCPreferencesRef) -> 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.

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 into_CFType(self) -> CFType

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.
