Module events 

events

Canonical event union for all cross-adapter events.

This module is the single source of truth for events used by SSE handlers and backend emitters. There is no Tauri-event branch: the desktop app consumes the same /api/events stream a browser tab does.

Structure

• app - Application-level events (model added/removed/updated)
• server - Model server lifecycle events

Download events are not a submodule here: AppEvent::Download wraps crate::download::DownloadEvent verbatim.

Wire Format

Events are serialized with a type tag for TypeScript compatibility:

{ "type": "server_started", "modelName": "Llama-2-7B", "port": 8080 }

server_error carries a structured error envelope (message, stable type discriminant, retryable flag) rather than a bare string, mirroring the HTTP layer’s ErrorResponse shape so SSE and HTTP clients agree on meaning:

{
  "type": "server_error",
  "modelId": 1,
  "modelName": "Llama-2-7B",
  "error": { "message": "...", "type": "service_unavailable", "retryable": true }
}
