Crate renamite_model 

Serializable document model + pure evaluator.

Group evaluation: pass 1 accumulates shape paths and applies modifiers in document order; pass 2 recurses/emits styles bottom-first so Scene.items is in painter’s order. Nodes live in a slotmap arena. Tree membership is attach/detach so undo/redo never changes a NodeId.

Structs

AssetId

ClipPath

Color

CompId

Composition

CompoundPath

Multi-contour geometry: boolean results and stroke expansions produce outer contours plus holes, which one VectorPath cannot represent.

DashSample

Document

FontAsset

A project font: the user-visible name, the logical family key text nodes reference, and the raw TTF/OTF bytes (saved/loaded inside the project).

Gradient

A gradient in the node’s local space. The evaluator folds the owning shape’s world transform into start/end before baking vertex colors.

GradientStop

One color anchor along a gradient axis. offset is in 0..=1.

GradientStops

Ordered gradient stops, sampled by sample. Kept small (usually 2-4).

ImageAsset

An embedded image asset. Stores the original encoded PNG/JPEG/WebP bytes and the decoded pixel dimensions established at import time.

ImageNode

KeyframeData

Serialized keyframe (for RestoreKeyframe / undo).

LayerProps

MaskProps

Node

NodeId

NodeTransformContext

Resolved transform information for one node at an editor frame.

Overrides

Per-frame property patch. Produced by clip/state-machine playback, consumed by evaluate_with. Never touches the document.

ScenePaint

Resolved, per-frame paint attached to a scene item. The renderer bakes this into mesh vertex colors at tessellation time.

ShapeKind

StarKind

StrokeCap

StrokeJoin

StyleKind

StylePaint

Paint on a style node: solid color or gradient. Animated so whole-list keyframes (e.g. stop-color morphs) work through the existing machinery.

TextAlign

Horizontal alignment of each line within the text block.

TrimMode

How Trim distributes [start, end] across multiple accumulated paths.

Functions

evaluate

evaluate_with

fill_style_for

The topmost fill style that paints shape: the last Fill style sibling in the closest ancestor scope that has one. Used by the inspector to edit a shape’s fill (the tool instead tracks the exact style via SceneItem). Children are z-ordered with index 0 = top, so the first Fill wins.

immediate_child_below

Return the immediate child of ancestor that contains descendant.

node_affine

The node’s own transform as an affine, ignoring group/accumulated transforms. Gradient handles are authored in this space and folded into world space with this same affine during evaluation, so the inverse maps world gradient handles back to local coordinates for editing.

node_is_ancestor

node_supports_opacity

Opacity multiplies into emission for every kind except masks, which only contribute a clip path and never emit paint. Modifier opacity applies to nested children (pass 3); it does not attenuate the pass-1 path effect.

node_supports_prop

Full per-prop support: section gate above, then path granularity. Anything returning false here is rejected by prop_mut/prop_ref.

node_supports_section

Whether kind honors anything in section. Sections group paths, so one arm covers a whole feature; per-path granularity (star Burst inner radius, solid-vs-gradient color, dash presence) stays in the descriptor filter and the prop_mut/prop_ref match arms.

node_supports_transform

Single source of truth for which props a node kind honors at render, keyed by section (not path string): one match instead of three parallel tables. prop_mut/prop_ref consult this, so unsupported edits fail loudly instead of writing dead values. Keep the arms in sync with eval_group/emit_style/apply_modifier.

node_transform_context

Resolve one attached node’s parent/world transforms.

nodes_bounds

Union bbox of all items belonging to nodes (selection bounds).

outer_select_target

Outermost selectable container for picked under comp.

pick

Low-level geometry hit: returns the leaf shape/text/image node.

pick_box

Nodes whose geometry is FULLY CONTAINED in the box (rubber-band semantics). min/max are normalized so drags in any direction work.

pick_box_selectable

Rubber-band variant of pick_selectable.

pick_selectable

pick_selectable_with_leaf

Topmost (outer, leaf) hit under pt, skipping locked subtrees.

prop_section_of

Sections of PropPaths a node kind supports, mirroring the section strings in renamite_behavior_common::inspect descriptors. None means the path belongs to no known section and is always rejected.

read_prop

selected_ancestor_for_pick

If picked belongs to an already-selected group/layer, return that selected ancestor instead of replacing it with the leaf shape.

selection_bounds

Union bounds of selected leaf nodes and all rendered descendants of selected groups/layers.

shape_path

The vector outline of a shape (or mask shape) node’s geometry in its own local coordinate space at frame, honoring any shape.* overrides.

stroke_style_for

Topmost stroke style in the closest ancestor scope that has one. Children are z-ordered with index 0 = top, so the first Stroke wins.

visit_prop

world_delta_to_parent

Convert a world-space drag delta to a node’s parent coordinate system.
