Struct style::font_face::FontFaceRuleData

pub struct FontFaceRuleData {
    pub family: Option<FamilyName>,
    pub sources: Option<Vec<Source>>,
    pub source_location: SourceLocation,
}

Data inside a @font-face rule.

https://drafts.csswg.org/css-fonts/#font-face-rule

Fields

family: Option<FamilyName>

The name of this font face

sources: Option<Vec<Source>>

The alternative sources for this font face.

source_location: SourceLocation

Line and column of the @font-face rule source code.

Implementations

impl FontFaceRuleData

pub fn empty(location: SourceLocation) -> Self

Create an empty font-face rule

pub fn decl_to_css(&self, dest: &mut CssStringWriter) -> Result

Serialization of declarations in the FontFaceRule

impl FontFaceRuleData

pub fn font_face(&self) -> Option<FontFace<'_>>

Per https://github.com/w3c/csswg-drafts/issues/1133 an @font-face rule is valid as far as the CSS parser is concerned even if it doesn’t have a font-family or src declaration.

However both are required for the rule to represent an actual font face.

Trait Implementations

impl Clone for FontFaceRuleData

fn clone(&self) -> FontFaceRuleData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FontFaceRuleData

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

Formats the value using the given formatter.

impl PartialEq<FontFaceRuleData> for FontFaceRuleData

fn eq(&self, other: &FontFaceRuleData) -> 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 ToCssWithGuard for FontFaceRuleData

fn to_css(
    &self,
    _guard: &SharedRwLockReadGuard<'_>,
    dest: &mut CssStringWriter
) -> Result

Serialize self in CSS syntax, writing to dest, using the given lock guard.

fn to_css_string(&self, guard: &SharedRwLockReadGuard<'_>) -> CssString

Serialize self in CSS syntax using the given lock guard and return a string.

impl ToShmem for FontFaceRuleData

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.
