value: Rc<T>
) -> Result<(), Error>
pub fn set_user_data<T: 'static>( &self, key: &'static UserDataKey<T>, value: Rc<T> ) -> Result<(), Error>
Attach user data to self
for the given key
.
sourcepub fn user_data<T: 'static>(
&self,
key: &'static UserDataKey<T>
) -> Option<Rc<T>>
pub fn user_data<T: 'static>( &self, key: &'static UserDataKey<T> ) -> Option<Rc<T>>
Return the user data previously attached to self
with the given key
, if any.
sourcepub fn user_data_ptr<T: 'static>(
&self,
key: &'static UserDataKey<T>
) -> Option<NonNull<T>>
pub fn user_data_ptr<T: 'static>( &self, key: &'static UserDataKey<T> ) -> Option<NonNull<T>>
Return the user data previously attached to self
with the given key
, if any,
without incrementing the reference count.
The pointer is valid when it is returned from this method,
until the cairo object that self
represents is destroyed
or remove_user_data
or set_user_data
is called with the same key.
sourcepub fn remove_user_data<T: 'static>(
&self,
key: &'static UserDataKey<T>
) -> Result<(), Error>
pub fn remove_user_data<T: 'static>( &self, key: &'static UserDataKey<T> ) -> Result<(), Error>
Unattached from self
the user data associated with key
, if any.
If there is no other Rc
strong reference, the data is destroyed.
