impl CGImageDestination

Source

pub unsafe fn copy_image_source( self: &CGImageDestination, isrc: &CGImageSource, options: Option<&CFDictionary>, err: *mut *mut CFError, ) -> bool

Methods from Deref<Target = CFType>§

Source

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.

Source

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.
