Enum FontFace 

pub enum FontFace {
    Generic(FontFamily),
    Named(String),
}

The face a run is set in: one of CSS’s four generics, or the family the author named.

A generic opens on every machine and a family name does not, which is the trade stated once in FontFamily’s own note. A named family is resolved through the platform’s font registry by the frontends that have one, and falls back to the body face where it is not installed.

Owned, because a family name is a String and this is what a gesture takes and a query answers — neither is per-glyph. What a glyph carries is FaceRef, the Copy half, whose name is looked up in the map’s FaceTable.

Implementations

impl FontFace

pub fn from_attrs(attrs: &[(String, Option<String>)]) -> Option<Self>

The face a run’s or block’s attributes name, if any — twig records it under data-font.

pub fn from_attr(value: &str) -> Option<Self>

Read a data-font value: one of the four generics, or any other non-empty string, which is a family name. Trimmed, and nothing else — a family name is what the author typed, and leaf has no table of real ones to check it against.

pub fn name(&self) -> Cow<'_, str>

The token twig spells it with, and what from_attr reads back — the generic’s CSS keyword, or the family name as given.

pub const fn generic(&self) -> Option<FontFamily>

The generic, for a menu asking which of its four rows to tick — None for a named family, which the menu shows as a row of its own.
