GLib type: Shared boxed type with reference counted clone semantics.

Implementations§

source§

impl FontFace

source

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

Return the inner pointer to the underlying C value.

source

pub unsafe fn from_glib_ptr_borrow<'a>( ptr: *const *const cairo_font_face_t, ) -> &'a Self

Borrows the underlying C value.

source§

impl FontFace

source

pub fn toy_create( family: &str, slant: FontSlant, weight: FontWeight, ) -> Result<FontFace, Error>

source

pub fn create_from_ft(face: &Face) -> Result<FontFace, Error>

Available on crate feature freetype only.

Creates a new font face for the FreeType backend from an already opened FreeType face.

source

pub fn create_from_ft_with_flags( face: &Face, load_flags: c_int, ) -> Result<FontFace, Error>

Available on crate feature freetype only.

Creates a new font face for the FreeType backend from an already opened FreeType face, additionally allowing you to pass flags to the underlying C API.

source

pub unsafe fn from_raw_full(ptr: *mut cairo_font_face_t) -> FontFace

source

pub unsafe fn from_raw_none(ptr: *mut cairo_font_face_t) -> FontFace

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.

Trait Implementations§

source§

impl Clone for FontFace

source§

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the reference. Dropping the reference will decrement it again.
