Module Vine 

Vine Protocol Implementation (Air)

Air’s Vine surface. Implements the gRPC protocol that runs on Air’s side of the bus - Air hosts AirVinegRPCService on [::1]:50053 so callers (Mountain, external clients, integration tests) can reach Air’s background services (indexing, downloads, updates, authentication).

Layout

• Generated - Air-local prost output for Air.proto. Air’s own service definitions (UpdateService, IndexingService, DownloaderService, AuthenticationService) live here.
• Server - Air’s gRPC server implementation (Server::AirVinegRPCService), wiring Air’s ApplicationState into the generated service traits.
• Error - re-exports the canonical [VineError] from the Vine crate and exposes Error::AirCompat alias constructors.

Re-exports from the Vine crate

For convenience, the most-used Vine crate items are re-exported at this module’s root so Air code can write use crate::Vine::{VineHost, IPCProvider}; without spelling out the workspace crate path:

• [VineHost] / [ApplicationStateAccess] / [IPCProvider] - embedder seam (Air’s ApplicationState implements these to host the Vine notification handler tree against Air’s runtime).
• [ProtocolVersion] / [DefaultRequestTimeoutMs] / [DefaultMaxMessageSize] / [DefaultAirAddress] - canonical protocol constants.
