Implementations

impl CGShading

pub fn new_axial( space: Option<&CGColorSpace>, start: CGPoint, end: CGPoint, function: Option<&CGFunction>, extend_start: bool, extend_end: bool, ) -> Option<CFRetained<CGShading>>

Available on crate features CGColorSpace and CGFunction only.

pub fn new_axial_with_content_headroom( headroom: c_float, space: Option<&CGColorSpace>, start: CGPoint, end: CGPoint, function: Option<&CGFunction>, extend_start: bool, extend_end: bool, ) -> Option<CFRetained<CGShading>>

Available on crate features CGColorSpace and CGFunction only.

pub fn new_radial( space: Option<&CGColorSpace>, start: CGPoint, start_radius: CGFloat, end: CGPoint, end_radius: CGFloat, function: Option<&CGFunction>, extend_start: bool, extend_end: bool, ) -> Option<CFRetained<CGShading>>

Available on crate features CGColorSpace and CGFunction only.

pub fn new_radial_with_content_headroom( headroom: c_float, space: Option<&CGColorSpace>, start: CGPoint, start_radius: CGFloat, end: CGPoint, end_radius: CGFloat, function: Option<&CGFunction>, extend_start: bool, extend_end: bool, ) -> Option<CFRetained<CGShading>>

Available on crate features CGColorSpace and CGFunction only.

pub fn content_headroom(shading: Option<&CGShading>) -> c_float

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 CGShading

fn as_ref(&self) -> &AnyObject

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

impl AsRef<CFType> for CGShading

fn as_ref(&self) -> &CFType

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

impl AsRef<CGShading> for CGShading

fn as_ref(&self) -> &Self

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

impl Borrow<AnyObject> for CGShading

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CGShading

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CGShading

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CGShading

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

Formats the value using the given formatter.

impl Deref for CGShading

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for CGShading

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 CGShading

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CGShading

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 CGShading

const ENCODING_REF: Encoding

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

impl Type for CGShading

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

where Self: Sized,

Increment the reference count of the receiver.

👎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

👎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.
