Crate weave_contracts 

WebSocket protocol types shared between edge-agent and weave-server.

Wire format: JSON text frames. Each frame is a single ServerToEdge or EdgeToServer value serialized as JSON. The runtime binds to a LAN IP and performs no authentication.

Structs

DeviceStateEntry

EdgeConfig

Complete config for one edge, pushed as a ConfigFull frame.

EdgeInfo

Identity + status for one connected (or previously-seen) edge.

FeedbackRule

Feedback rule: service state → device visual feedback.

Glyph

A named Nuimo LED glyph. pattern is a 9x9 ASCII grid compatible with nuimo::Glyph::from_str (* = LED on, anything else = off, rows separated by \n).

Mapping

A device-to-service mapping. Mirrors the structure already used by weave-server’s REST API. edge_id is new; all other fields retain their existing semantics.

Route

One input-to-intent route inside a mapping.

ServiceStateEntry

TargetCandidate

One entry in Mapping::target_candidates. During selection mode the device displays glyph and, on confirm, the mapping’s service_target is replaced with target.

UiSnapshot

Initial full state sent on /ws/ui connect. Subsequent changes arrive as UiFrame variants.

Enums

CommandResult

Outcome of an EdgeToServer::Command.

EdgeToServer

Frames sent from an edge-agent to weave-server.

ErrorSeverity

Severity classification for EdgeToServer::Error and UiFrame::Error.

PatchOp

ServerToEdge

Frames sent from weave-server to an edge-agent.

UiFrame

Frames sent from weave-server to a Web UI client on /ws/ui.
