pub fn debug_cap_xrender_version( &self, _major_version: i32, _minor_version: i32, )

Available on crate features xlib or xcb only.

pub fn debug_get_precision(&self) -> i32

Available on crate features xlib or xcb only.

pub fn debug_set_precision(&self, _precision: i32)

Available on crate features xlib or xcb only.

pub fn status(&self) -> 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.

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>

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