yaak-mountain-loop/crates-tauri/yaak-app-client/src/rpc_ext.rs

//! The client's RPC surface: every command, wired to its Tauri implementation.
//!
//! The *shape* of the surface — command names, request payloads, response
//! types — is declared once in `yaak_rpc_schema`, which is also where the
//! TypeScript bindings come from. This module supplies the desktop's half: an
//! adapter per command that turns a `ClientCtx` and a request struct into a
//! call on the existing implementation, and the single `rpc` Tauri command that
//! is the only way the frontend reaches any of it — one envelope,
//! `{ cmd, payload }`, exactly like the proxy app.
//!
//! Command bodies live in one of two places. Host-independent ones are in
//! `yaak_commands`, written against its `Host` trait, which `ClientCtx`
//! implements below; their adapters are one line. The rest still have their
//! natural Tauri signatures (window, app handle, managed state) and their
//! adapters unpack the request for them. Either way the wire format stays
//! transport-agnostic: another host builds its router from the same schema
//! with its own `Host`, and the frontend cannot tell.
