========================================================================== Node Manifest

Complete node definition manifest

This is returned by get-manifest() and contains all metadata needed for the host to:

1. Calculate GPU memory layout (std140)
2. Build UI widgets
3. Validate shader bindings
4. Allocate resources
5. Register available actions
6. Display plugin information in marketplace/browser

Fields

api_version: u32

API version (must match host’s expected version)

display_name: String

Display name shown in node palette/graph

version: String

Plugin metadata for distribution Version string (e.g., “1.0.0”, “2.1.3-beta”)

author: String

Author/organization name

description: String

Human-readable description

category: NodeCategory

Category for UI organization

tags: Vec<String>

Searchable tags (e.g., [“glitch”, “retro”, “vhs”])

model: ExecutionModel

Execution model (fragment or compute)

parameters: Vec<ShaderParam>

List of parameters Host calculates std140 layout from this list Order matters for struct field layout!

ports: Vec<NodePort>

Port definitions (texture + control) Texture ports map to @group(2) @binding(N) in shader

output_resolution_scale: f32

Output resolution scale relative to input 1.0 = same size, 0.5 = half size, 2.0 = double size

output_hint: Option<OutputHint>

Output format hint (optional) Default (None/auto): Rgba8Unorm for all intermediate textures Use hdr/high-precision only for effects requiring wider dynamic range See output-hint variant documentation for details

actions: Vec<ActionDef>

List of available actions Standard actions (reset, randomize) are handled by host Custom actions require execute-custom-action implementation

embedded_textures: Vec<EmbeddedTexture>

Embedded textures bundled in this plugin (optional)

These textures are decoded and registered by the host at load time. Use this for asset packs, LUT collections, or fallback images that should be distributed together with the plugin.

Each texture is identified by its key and can be referenced via the TextureSource node or parameter-driven texture switching.
