Crate gpui_kit_material 

Material 3 adapters for Longbridge GPUI Kit.

The kit is layered so each layer can be replaced without touching the ones above it:

Layer	Module	Holds
Color	color (gpui-kit-material-color)	palettes, roles, scheme derivation
Theme	theme	the painted scheme, palette transitions, theme::color
Tokens	tokens	shape, type scale, layout metrics, elevation, state layers
Motion	motion	M3 springs, entrances, retargetable values
Icons	icons	Google Material Symbols through icons::Assets
Components	components	Material presentation over Kit components and Base parts

Reuse [gpui_kit::component] controls where their presentation hooks meet the Material contract; [gpui_base] supplies behavior for uncovered parts. This kit owns the Material appearance and motion, not another generic UI runtime.

Call gpui_kit::init and then init once at startup. Use Kit’s open_window for the single Root, register icons::Assets, and initialize theme::init_component_theme before Root’s first render. Advance theme::advance_component_theme from input events and pre-frame callbacks. Base-only consumers can paint with theme::apply_scheme at the start of each root render.

Re-exports

pub use gpui_kit_material_color as color;

Modules

components

Material components. Each module documents the M3 component it implements and what remains for M3 Expressive (docs/ROADMAP.md).

icons

Material Symbols rendered through Longbridge Kit’s Component Icon.

motion

The motion vocabulary: M3 springs, entrances and retargetable values.

prelude

The roles, tokens and components most pages need, including the theme::color lookup. The crate root’s color is the color module.

theme

The painted scheme: what color returns on the current frame.

tokens

Design tokens. Geometry is in px where it must not follow the text scale and in rems (14px = 1rem at 100%) where it shares a ruler with text.

Functions

init

Register the kit’s key bindings. Call once, before opening windows.
