Enum FontId 

pub enum FontId {
    Ui,
    Serif,
    Monospace,
    Family(String),
}

Stable, portable font identifier used by the UI/runtime.

This is intentionally a semantic identifier (not a font database index) so that it remains stable across runs and portable to wasm/sandboxed environments.

Variants

Ui

Built-in “system UI” font alias (implementation-defined).

Serif

Built-in serif font alias (implementation-defined).

Monospace

Built-in monospace font alias (implementation-defined).

Family(String)

A named font family resolved by the backend (best-effort).

Implementations

impl FontId

pub fn ui() -> Self

pub fn serif() -> Self

pub fn monospace() -> Self

pub fn family(name: impl Into<String>) -> Self

Trait Implementations

impl Clone for FontId

fn clone(&self) -> FontId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontId

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

Formats the value using the given formatter.

impl Default for FontId

fn default() -> FontId

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FontId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FontId

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 FontId

fn eq(&self, other: &FontId) -> 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 FontId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for FontId
