) -> Result<MappedImageSurface, Status>

pub fn set_user_data<T: 'static>(
    &self,
    key: &'static UserDataKey<T>,
    value: Rc<T>
)

Attach user data to self for the given key.

pub fn get_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 get_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>)

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

pub fn flush(&self)

pub fn finish(&self)

pub fn get_type(&self) -> SurfaceType
