Struct style::values::computed::font::FontFamilyList

#[repr(C)]
pub struct FontFamilyList {
    pub list: ArcSlice<SingleFontFamily>,
}

A list of font families.

Fields

list: ArcSlice<SingleFontFamily>

The actual list of font families specified.

Implementations

impl FontFamilyList

pub fn iter(&self) -> impl Iterator<Item = &SingleFontFamily>

Return iterator of SingleFontFamily

pub(crate) fn prioritize_first_generic_or_prepend( &mut self, generic: GenericFontFamily, )

If there’s a generic font family on the list which is suitable for user font prioritization, then move it ahead of the other families in the list, except for any families known to be ligature-based icon fonts, where using a generic instead of the site’s specified font may cause substantial breakage. If no suitable generic is found in the list, insert the default generic ahead of all the listed families except for known ligature-based icon fonts.

pub(crate) fn needs_user_font_prioritization(&self) -> bool

Returns whether we need to prioritize user fonts.

pub fn single_generic(&self) -> Option<GenericFontFamily>

Return the generic ID if it is a single generic font

Trait Implementations

impl Clone for FontFamilyList

fn clone(&self) -> FontFamilyList

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FontFamilyList

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FontFamilyList

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FontFamilyList

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FontFamilyList

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for FontFamilyList

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToComputedValue for FontFamilyList

where ArcSlice<SingleFontFamily>: ToComputedValue<ComputedValue = ArcSlice<SingleFontFamily>>,

type ComputedValue = FontFamilyList

The computed value type we’re going to be converted to.

fn from_computed_value(from: &Self::ComputedValue) -> Self

Convert a computed value to specified value form.

fn to_computed_value(&self, context: &Context<'_>) -> Self::ComputedValue

Convert a specified value to a computed value, using itself and the data inside the Context.

impl ToResolvedValue for FontFamilyList

where ArcSlice<SingleFontFamily>: ToResolvedValue<ResolvedValue = ArcSlice<SingleFontFamily>>,

type ResolvedValue = FontFamilyList

The resolved value type we’re going to be converted to.

fn from_resolved_value(from: Self::ResolvedValue) -> Self

Convert a resolved value to resolved value form.

fn to_resolved_value(self, context: &Context<'_>) -> Self::ResolvedValue

Convert a resolved value to a resolved value.

impl ToShmem for FontFamilyList

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

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

impl Eq for FontFamilyList
