Struct core_graphics::color::CGColor

pub struct CGColor(_);

Methods

impl CGColor

pub fn rgb(red: CGFloat, green: CGFloat, blue: CGFloat, alpha: CGFloat) -> Self

Trait Implementations

impl Drop for CGColor

fn drop(&mut self)

Executes the destructor for this type.

impl Clone for CGColor

fn clone(&self) -> CGColor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for CGColor

impl PartialEq<CGColor> for CGColor

fn eq(&self, other: &CGColor) -> 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 ConcreteCFType for CGColor

impl TCFType for CGColor

type Ref = CGColorRef

The reference type wrapped inside this type.

fn as_concrete_TypeRef(&self) -> CGColorRef

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: CGColorRef) -> 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: CGColorRef) -> 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) -> i64

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) -> u64

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.
