pub unsafe fn from_raw_borrow(ptr: *mut cairo_device_t) -> Borrowed<Device>

pub unsafe fn from_raw_full(ptr: *mut cairo_device_t) -> Device

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.

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.

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.

pub fn remove_user_data<T: 'static>(
    &self,
    key: &'static UserDataKey<T>
) -> Result<(), Error>

Unattach from self the user data associated with key, if any. If there is no other Rc strong reference, the data is destroyed.
