Struct FontFace 

pub struct FontFace { /* private fields */ }

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

Implementations

impl FontFace

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

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow(ptr: &*mut cairo_font_face_t) -> &Self

Borrows the underlying C value.

impl FontFace

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

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

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

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

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

pub fn toy_get_slant(&self) -> FontSlant

pub fn toy_get_weight(&self) -> FontWeight

pub fn type_(&self) -> FontType

pub fn reference_count(&self) -> usize

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.

Trait Implementations

impl Clone for FontFace

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.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FontFace

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<FontFace> for Value

fn from(s: FontFace) -> Self

Converts to this type from the input type.

impl HasParamSpec for FontFace

type ParamSpec = ParamSpecBoxed

type SetValue = FontFace

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecBoxedBuilder<'_, FontFace>

fn param_spec_builder() -> Self::BuilderFn

impl StaticType for FontFace

fn static_type() -> Type

Returns the type identifier of Self.
