Struct InMemoryFontSystem 

pub struct InMemoryFontSystem { /* private fields */ }

Font system backed by an in process font map, for embedded and browser environments.

Implementations

impl InMemoryFontSystem

pub fn new() -> Self

Create an empty in memory font system.

pub fn with_fallback_shaping(self) -> Self

Enable deterministic fallback shaping for tests and bootstrap, without a native shaping engine.

pub fn with_font( self, family: impl Into<String>, bytes: impl Into<Vec<u8>>, ) -> Self

Add a font by family name and return self.

pub fn insert(&mut self, family: impl Into<String>, bytes: impl Into<Vec<u8>>)

Insert or replace a font.

pub fn with_font_data(self, font: FontData) -> Self

Add a font the application already constructed, sharing its parsed faces, and return self.

pub fn insert_font_data(&mut self, font: FontData)

Insert or replace an application owned font keyed by its canonical name; parses stay shared.
