pub unsafe fn new( info: *mut c_void, bounds: CGRect, matrix: CGAffineTransform, x_step: CGFloat, y_step: CGFloat, tiling: CGPatternTiling, is_colored: bool, callbacks: *const CGPatternCallbacks, ) -> Option<CFRetained<CGPattern>>

only.Methods from Deref<Target = CFType>§
Sourcepub fn downcast_ref<T>(&self) -> Option<&T>where
T: ConcreteType,
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.
Sourcepub fn retain_count(&self) -> usize
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 CFNumber
s, small CFString
s etc.) may
not have a normal retain count for optimization purposes, and can
return usize::MAX
in that case.
