Enum ChromeRole 

pub enum ChromeRole {
    Bar,
    Panel,
    Control,
    Selector,
    Object,
}

What a chrome surface is. Picking the role fixes radius, surface and border together, so two surfaces of the same role are consistent without their authors having to coordinate.

Variants

Bar

Docked chrome fixed to a screen edge — the top bar.

Panel

A floating surface opened over content — quick settings, the palette, a popover, a sheet.

Control

Something inside a Bar or Panel that you press — an action tile, a list row, a slider, a field.

Selector

One of a set you choose between — a tab pill, the tray pill, a workspace chip, a strip segment, a scope chip.

Object

A thing that holds app content — a window card or tile.

Implementations

impl ChromeRole

pub fn radius(self, theme: &Theme, height: f64) -> f64

height is used only by ChromeRole::Selector, a capsule that resolves to half its own height rather than the degenerate radii.full (9999), which breaks the rounded-rect path on a short rect.

pub fn surface(self, theme: &Theme) -> AlphaColor<Srgb>

The role’s opaque surface colour. Reads the semantic surface tokens, never a ramp slot, so it survives a theme whose author never saw this code. A Panel’s body is painted in the floating material (crate::floating_surface::paint_material); this is the colour that material tints with, and what it is where blur is unavailable.

Trait Implementations

impl Clone for ChromeRole

fn clone(&self) -> ChromeRole

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChromeRole

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for ChromeRole

fn eq(&self, other: &ChromeRole) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
