Crate icons 

icons — the Lucide set, ported into typed constants. Reached as bezel::icons.

use ui::icons::{self, navigation};

icons::icon(navigation::Compass).size(px(16.0)).text_color(theme.text_muted)

icon returns a gpui Svg, so it colors with text_color and sizes like any element. ui’s theme.icon(..) is the same builder with both supplied from the ladder and the palette, which is what app code should reach for.

What a component takes

Icon is the value, and it erases where the drawing came from — a glyph compiled in, the app’s Icon::asset source, or Icon::file off disk. Components take impl Into<Icon>, so glyph::Search passes as itself and neither the component nor its signature learns which it got. SwiftUI’s Image erases its sources the same way.

An Icon carries no size and no colour. Those are the environment’s, which here is the component: a menu row’s glyph is the row’s metric, not the caller’s.

The set

Modules are Lucide’s categories and constants are Lucide’s names, both generated by build.rs from a pinned release — there is no curated list to drift from upstream. A glyph Lucide files under two categories is one constant re-exported twice, so glyph holds each exactly once.

A constant is the SVG itself rather than a path into an asset source, which is what lets the linker drop an icon the app never names: the set costs a binary only the glyphs it paints. Nothing registers with with_assets.

Paying for what you paint

One feature per Lucide category, named as Lucide names it, and full is all 42. Nothing is on by default. Cargo unions features across a graph, so a category a dependency turns on is the floor for everyone below it — ui needs arrows, notifications and text.

CATEGORIES is every enabled category and its icons, for an icon browser. Naming it is what pins the enabled set, so an app that only paints icons never mentions it and keeps the linker’s dead-code pass.

Modules

glyph

Every enabled glyph, under Lucide’s own name.

Structs

Icon

What to paint: a drawing, and the variant of it. Every component that takes an icon takes this, so a glyph and an app’s own file are one signature.

Constants

CATEGORIES

Every enabled category and its icons.

Functions

icon

An icon element. Size and colour are the caller’s (.size(..), .text_color(..)) — an Svg with neither paints nothing, which is why ui’s theme.icon(..) supplies both and this is the floor under it.

solid

icon, painted solid — icons::solid(glyph::Play).

Type Aliases

Icons

One category’s icons, each a name and the SVG itself.
