Struct Layer 

pub struct Layer {
    pub system: SystemKind,
    pub join: LayerJoin,
    pub blend: LayerBlend,
    pub mix: Option<Binding>,
    pub params: Vec<Binding>,
    pub per_vertex: Vec<Binding>,
    pub config: Option<GeneratorConfig>,
}

The optional second scene layer (ADR-0090 / Plan 0076): a full authoring surface — its own system, params, bindings, [layer.smoothing] and structural tables — joined to the composite at LayerJoin. The preset’s single [palette] serves both layers (one colour language, one baked LUT), and layer params are namespaced to the layer: they reach the layer’s scene only, never the main scene’s first-owner-wins routing and never the compositing stages, which belong to the preset as a whole.

Fields

system: SystemKind

The built-in system this layer drives.

join: LayerJoin

Where the layer joins the composite.

blend: LayerBlend

How an over layer blends in (ignored, with a load warning, on an under join — there is no junction for it to apply at).

mix: Option<Binding>

The bindable mix amount at the over join (ADR-0090): how much of the layer the blend applies, evaluated per frame like any binding so audio can surge the second layer. None — the default — is full strength.

params: Vec<Binding>

The layer’s parameter bindings, name-sorted like the preset’s own.

per_vertex: Vec<Binding>

The layer’s [layer.per_vertex] bindings — see Preset::per_vertex.

config: Option<GeneratorConfig>

The layer’s declarative structural config (ADR-0007), from its own [layer.curve] / [layer.generator] / [layer.particles] / [layer.spectrum] tables — validated by the same per-system rules as the top level.

Trait Implementations
