Enum StockShader 

pub enum StockShader {
    SolidQuad,
    RoundedRect,
    Text,
    DividerLine,
    Image,
    Spinner,
    Skeleton,
    ProgressIndeterminate,
}

Shipped shader inventory. See docs/SHADER_VISION.md for the shader model.

Variants

SolidQuad

Flat colored rect. Fallback / debug.

RoundedRect

Fill + stroke + radius + shadow + focus ring. The workhorse — handles ~80% of UI surfaces. Focus indicator is a uniform on this shader, not a separate pipeline (see widget_kit.md).

Text

Alpha-mask glyph rendering. Backends sample per-glyph bitmaps from a crate::text::atlas::GlyphAtlas page texture and tint by per-glyph color. The historical TextSdf name was aspirational; the actual rasterization is alpha-coverage via swash.

DividerLine

Antialiased 1px line.

Image

Per-image raster sampling. Backend binds a per-image texture at group 1 and the fragment shader composes sampled * tint with rounded-corner AA. See crate::image::Image for the data side.

Spinner

Indeterminate loading spinner — circular SDF arc swept around a dim track, animated by frame.time. Continuous: any node bound to this shader keeps needs_redraw set so the host idle loop keeps ticking.

Skeleton

Pulsing loading placeholder — a rounded rect with a cosine alpha breathe (0.5 → 1.0 → 0.5 over 2 s by default) matching shadcn’s animate-pulse. Continuous.

ProgressIndeterminate

Indeterminate linear progress — a track with a small bar sliding left-to-right on loop, for in-line “still working…” feedback when no completion ratio is known. Continuous.

Implementations

impl StockShader

pub fn name(self) -> &'static str

pub fn is_continuous(self) -> bool

Whether this shader’s output depends on frame.time, i.e. the host must keep redrawing for it to animate. Read by [crate::runtime::RunnerCore::prepare_layout] when computing needs_redraw.

Trait Implementations

impl Clone for StockShader

fn clone(&self) -> StockShader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StockShader

impl Debug for StockShader

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

Formats the value using the given formatter.

impl Eq for StockShader

impl Hash for StockShader

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StockShader

fn eq(&self, other: &StockShader) -> 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.
