graphitepdf-font 0.4.0

Overview

graphitepdf-font models font families, variants, sources, standard fonts, emoji sources, and font loading for the GraphitePDF workspace.

Scope

graphitepdf-font contains:

• FontDescriptor, FontStyle, and FontWeight
• FontSource for local, remote, data-URI, and standard-font inputs
• registration types such as FontRegistration and FontFamilyRegistration
• FontStore for lookup, loading, emoji URL resolution, and hyphenation callbacks

Installation

cargo add graphitepdf-font

API Summary

Example

use graphitepdf_font::{FontDescriptor, FontRegistration, FontSource, FontStore, StandardFont};

#[tokio::main]
async fn main() -> graphitepdf_font::Result<()> {
    let mut store = FontStore::new();
    store.register_font(FontRegistration::new(
        "Helvetica",
        FontSource::standard(StandardFont::Helvetica),
    ))?;

    let descriptor = FontDescriptor::new("Helvetica");
    let _loaded = store.load(&descriptor).await?;

    Ok(())
}

Design Principles

• keep font identity and loading separate from text layout policy
• support multiple source types without hiding fallibility
• expose standard-font behavior as first-class data
• make fallback and emoji integration explicit rather than magical

Role In GraphitePDF

This crate is a shared service used by textkit, layout, render, style, and kit. It is the workspace's central place for describing and resolving fonts.
