Implementations

impl CGDisplayMode

pub unsafe fn width(mode: Option<&CGDisplayMode>) -> usize

pub unsafe fn height(mode: Option<&CGDisplayMode>) -> usize

pub unsafe fn pixel_encoding( mode: Option<&CGDisplayMode>, ) -> Option<CFRetained<CFString>>

👎Deprecated: No longer supported

pub unsafe fn refresh_rate(mode: Option<&CGDisplayMode>) -> c_double

pub unsafe fn io_flags(mode: Option<&CGDisplayMode>) -> u32

pub unsafe fn io_display_mode_id(mode: Option<&CGDisplayMode>) -> i32

pub unsafe fn is_usable_for_desktop_gui(mode: Option<&CGDisplayMode>) -> bool

impl CGDisplayMode

pub unsafe fn pixel_width(mode: Option<&CGDisplayMode>) -> usize

pub unsafe fn pixel_height(mode: Option<&CGDisplayMode>) -> usize

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.

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.

Trait Implementations

impl AsRef<AnyObject> for CGDisplayMode

fn as_ref(&self) -> &AnyObject

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

impl AsRef<CFType> for CGDisplayMode

fn as_ref(&self) -> &CFType

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

impl AsRef<CGDisplayMode> for CGDisplayMode

fn as_ref(&self) -> &Self

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

impl Borrow<AnyObject> for CGDisplayMode

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CGDisplayMode

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CGDisplayMode

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CGDisplayMode

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

Formats the value using the given formatter.

impl Deref for CGDisplayMode

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for CGDisplayMode

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 CGDisplayMode

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CGDisplayMode

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 CGDisplayMode

const ENCODING_REF: Encoding

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

impl Type for CGDisplayMode

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

where Self: Sized,

Increment the reference count of the receiver.

fn as_concrete_TypeRef(&self) -> &Self

👎Deprecated: this is redundant

Helper for easier transition from the core-foundation crate.

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

where Self: Sized,

👎Deprecated: use CFRetained::retain

Helper for easier transition from the core-foundation crate.

fn as_CFTypeRef(&self) -> &CFType

where Self: AsRef<CFType>,

👎Deprecated: this is redundant (CF types deref to CFType)

Helper for easier transition from the core-foundation crate.

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

where Self: Sized,

👎Deprecated: use CFRetained::from_raw

Helper for easier transition from the core-foundation crate.
