Modules

protocol

Async request/response protocol — the engine-side dispatch surface.

rendering

Rendering, view transform, thumbnails, undo/redo, and async readback polling.

save

.darkly save flow — async readback of every pixel-bearing texture plus the composite, gathered into a SaveBundle for JS to encode and zip.

types

FFI/serialization types — serde-serializable for any WASM bridge.

Structs

BrushPerfDelta

Per-interval brush perf delta returned by crate::engine::DarklyEngine::drain_brush_perf_delta. Scalars are differences against the previous snapshot; vectors are taken whole-cloth from the current counter (and reset to empty there).

DarklyEngine

ExportImageResult

Completed export readback — drained by poll_export_result.

FrameRenderPhases

Most recent engine.render() sub-phase timings, in microseconds. Overwritten each frame. Read by the WASM bridge’s slow-frame log so the breakdown is surfaced alongside the bridge-side drain/render timing without having to plumb a return value out of render.

LoadDocument

Public marker re-export so the WASM bridge can name the engine-side “loaded document” capability without importing the load module directly. Empty today; reserved for future expansion (e.g. progress callbacks).

Enums

PreviewKind

Which kind of effect a picker preview is generating. Keys the shared previews map alongside the effect’s 'static type id, so a veil and a void that happen to share a type-id string never collide.
