Methods from Deref<Target = FontFace>§

source

pub fn as_ptr(&self) -> *mut cairo_font_face_t

Return the inner pointer to the underlying C value.

source

pub fn to_raw_none(&self) -> *mut cairo_font_face_t

source

pub fn toy_get_family(&self) -> Option<String>

source

pub fn toy_get_slant(&self) -> FontSlant

source

pub fn toy_get_weight(&self) -> FontWeight

source

pub fn type_(&self) -> FontType

source

pub fn reference_count(&self) -> usize

source

pub fn synthesize(&self) -> FtSynthesize

source

pub fn set_synthesize(&self, synth_flags: FtSynthesize)

source

pub fn unset_synthesize(&self, synth_flags: FtSynthesize)

source

pub fn status(&self) -> Result<(), Error>

source

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.

source

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.

source

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.

source

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.
