Crate martensite 

The Martensite GUI Framework.

Martensite is a retained-mode, GPU-accelerated graphical user interface framework for Rust. It provides deterministic generational arena storage, fine-grained reactive signals, and a GPU rendering pipeline built on WGPU and Vello.

Getting started

Add martensite to your Cargo.toml:

[dependencies]
martensite = "0.22.0"

Examples

Import the prelude for the most commonly used types:

use martensite::prelude::*;

Architecture

Each subsystem lives in its own crate, re-exported here for convenience:

• core — generational widget arena, WidgetId, HotNode, ColdNode
• reactive — push-pull signal DAG with cycle detection
• layout — Taffy-based flexbox and grid layout
• wgpu — WGPU device and surface management
• render — Vello GPU rendering pipeline
• text — HarfBuzz shaping, BiDi, and font fallback
• access — AccessKit native accessibility integration
• window — Winit multi-window management
• focus — Focus traversal and management
• clipboard — Clipboard integration
• dnd — Drag and drop
• theme — Oklab color theme system
• motion — Spring physics animation
• history — Undo/redo history
• l10n — Localization via Fluent
• macros — Procedural macros
• blessed — Curated tier-1 widgets (DataTable, DockTree, Chart, CodeEditor)
• shell — System backdrops, snap layouts, CSD, and system tray
• devtools — Tracing spans, GPU timestamps, and the in-app diagnostic HUD
• design_lint — Standards-backed design linting over paint scope geometry
• app — Application builder and software fallback configuration
• Testing utilities are available via the martensite-test dev-dependency.

Modules

app

Application builder and runtime configuration.

icons

Native stroke-icon vocabulary: the BUILTIN icon pack, the IconPack/IconSet resolution chain, and the name constants — external packs plug in as overlays over the builtin fallback.

prelude

Convenience prelude re-exporting the most commonly used Martensite types.

runner

Canonical windowed runner: winit ApplicationHandler + GPU

text_paint

Foundational widgets (Button, CheckBox, Container, Flex, MediaView, Stack, Text, TextInput).

widgets

Base widgets: Container, Flex, Stack, Text.
