#[repr(transparent)]
pub struct AttrFontFeatures { /* private fields */ }

Implementations

impl AttrFontFeatures

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

Return the inner pointer to the underlying C value.

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

Borrows the underlying C value.

pub unsafe fn from_glib_ptr_borrow_mut<'a>( ptr: *mut *mut PangoAttrFontFeatures ) -> &'a mut Self

Borrows the underlying C value mutably.

impl AttrFontFeatures

pub fn new(features: &str) -> Self

Create a new font features tag attribute.

You can use this attribute to select OpenType font features like small-caps, alternative glyphs, ligatures, etc. for fonts that support them.

features

a string with OpenType font features, with the syntax of the CSS font-feature-settings property

Returns

the newly allocated Attribute, which should be freed with Pango::Attribute::destroy()

pub fn features(&self) -> GString

Methods from Deref<Target = Attribute>

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

Return the inner pointer to the underlying C value.

pub fn attr_class(&self) -> AttrClass

pub fn type_(&self) -> AttrType

pub fn start_index(&self) -> u32

pub fn end_index(&self) -> u32

pub fn set_start_index(&mut self, index: u32)

pub fn set_end_index(&mut self, index: u32)

pub fn downcast_ref<T: IsAttribute>(&self) -> Option<&T>

Trait Implementations

impl AsRef<Attribute> for AttrFontFeatures

fn as_ref(&self) -> &Attribute

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for AttrFontFeatures

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttrFontFeatures

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

Formats the value using the given formatter.

impl Deref for AttrFontFeatures

type Target = Attribute

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for AttrFontFeatures

fn deref_mut(&mut self) -> &mut Attribute

Mutably dereferences the value.

impl From<AttrFontFeatures> for Attribute

fn from(attr: AttrFontFeatures) -> Attribute

Converts to this type from the input type.

impl From<AttrFontFeatures> for Value

fn from(o: AttrFontFeatures) -> Self

Converts to this type from the input type.

impl HasParamSpec for AttrFontFeatures

type ParamSpec = ParamSpecBoxed

type SetValue = AttrFontFeatures

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

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

fn param_spec_builder() -> Self::BuilderFn

impl IsAttribute for AttrFontFeatures

const ATTR_TYPES: &'static [AttrType] = _

fn upcast(self) -> Attribute

fn upcast_ref(&self) -> &Attribute

impl PartialEq<AttrFontFeatures> for AttrFontFeatures

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StaticType for AttrFontFeatures

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for AttrFontFeatures

impl Send for AttrFontFeatures

impl Sync for AttrFontFeatures
