Struct core_graphics::display::CFDictionary [−][src]
Implementations
Returns a CFMutableDictionary
pointing to the same underlying dictionary as this immutable one.
This should only be used when the underlying dictionary is mutable.
Returns the same dictionary, but with the types reset to void pointers.
Equal to to_untyped
, but is faster since it does not increment the retain count.
pub fn find<T>(&'a self, key: T) -> Option<ItemRef<'a, V>> where
T: ToVoid<K>,
V: FromVoid,
K: ToVoid<K>,
Panics
Panics if the key is not present in the dictionary. Use find
to get an Option
instead
of panicking.

Equal to to_CFPropertyList
, but consumes self and avoids changing the reference count. Read more
Returns the object as its concrete TypeRef.
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. Read more
Returns the object as a raw CFTypeRef
. The reference count is not adjusted.
Returns an instance of the object, wrapping the underlying CFTypeRef
subclass. Use this

Returns the object as a wrapped CFType
. The reference count is incremented by one.
Returns the object as a wrapped CFType
. Consumes self and avoids changing the reference
count. Read more
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. Read more
Returns true if this value is an instance of another type.
