TiTanFont

Fast TrueType font rasterizer in pure Rust

🦀 Pure Rust • 📦 Zero Dependencies • ⚙️ no_std

Quick Start

use titanf::TrueTypeFont;

fn main() {
    let font_data = include_bytes!("Roboto-Medium.ttf");
    let mut font = TrueTypeFont::load_font(font_data);

    // Render a character
    let (metrics, bitmap) = font.get_char::<false>('A', 16.0);

    // Enable built-in glyph caching
    let (metrics, bitmap) = font.get_char::<true>('B', 16.0);
    //                                      ^^^^ caching enabled
}

Add to your Cargo.toml:

[dependencies]

titanf = "x.x.0"

Features

🚀 Fast — Up to 100,000 glyphs/second at 16px
🦀 Zero Dependencies — Pure Rust, no external crates
📦 no_std — Works in bare-metal environments (requires alloc)
💯 Stable Rust — No nightly features, no unsafe code
🔧 Built-in Parser — Handles TrueType tables: cmap, glyf, head, hhea, hmtx, kern, loca, maxp

Benchmarks

All benchmarks run on the same hardware with consistent methodology:

Identical parameters across rasterizers
Results wrapped in black_box() to prevent optimization
Multiple runs averaged for consistency
No caching enabled

Run benchmarks yourself:
