Module wire 

Leptos-free wire types spoken between a page and its render worker, compiled under either the leptos or the offscreen feature. Pixel quantities are physical surface pixels (CSS pixels times the device pixel ratio), origin at the canvas top-left.

ToWorker and FromWorker are the control plane the host owns: init, resize, input, picking, and status. Application traffic rides a separate envelope field as the message pair a WorkerProtocol impl declares, with optional binary Attachments transferred alongside.

Structs

SelectedEntity

The selected entity as reported to the page: display data only. The worker keeps the live selection and hands it to the custom message handler; nothing here resolves back into an entity.

ValueProtocol

The untyped protocol: JSON values both ways. What run_offscreen and the default use_engine speak, so a small app never declares message enums.

Enums

FromWorker

ToWorker

TouchPhase

Constants

APP_KEY

Envelope field carrying a serialized application message: the WorkerProtocol::Incoming type page to worker, the WorkerProtocol::Outgoing type worker to page.

ATTACHMENTS_KEY

Envelope field carrying named binary payloads as a { name: Uint8Array } object whose buffers ride the transfer list.

CANVAS_KEY

Envelope field carrying the transferred OffscreenCanvas (on Init only).

MESSAGE_KEY

Envelope field carrying the serialized control message in every postMessage.

Traits

WorkerProtocol

The application message pair a page and its worker speak over the APP_KEY envelope field, from the worker’s point of view: Incoming arrives from the page, Outgoing returns to it. The control plane (init, resize, input, picking, status) is not part of the protocol; the host owns it. Both types serialize and deserialize because each crosses the wire in one direction and is decoded on the other side.

Type Aliases

Attachments

Named binary payloads accompanying an application message: dropped asset bytes, a glTF with its resources, a saved file.
