Struct FontRegistry 

pub struct FontRegistry { /* private fields */ }

A font registry that maps font family + weight + style to font data.

Implementations

impl FontRegistry

pub fn new() -> Self

pub fn resolve(&self, families: &str, weight: u32, italic: bool) -> &FontData

Look up a font by family name (or comma-separated fallback chain), falling back to Helvetica if none match.

Supports CSS-style font family lists: "Inter, Helvetica" tries Inter first, then Helvetica. Quoted families are unquoted automatically.

pub fn resolve_for_char( &self, families: &str, ch: char, weight: u32, italic: bool, ) -> (&FontData, String)

Resolve a font for a specific character from a comma-separated fallback chain.

Walks the families in order, returning the first font that has a glyph for ch. Falls back to Helvetica if no font covers the character. Returns a tuple of (font_data, resolved_single_family_name).

pub fn register( &mut self, family: &str, weight: u32, italic: bool, data: Vec<u8>, )

Register a custom font.

pub fn iter(&self) -> impl Iterator<Item = (&FontKey, &FontData)>

Iterate over all registered fonts.
