codeoid-protocol 0.3.0

//! Codeoid wire protocol — Rust port of `src/protocol/types.ts` from the daemon.
//!
//! This crate is pure data: no I/O, no async, no Tokio. It defines serde-
//! compatible types for every message that flows between a Codeoid client and
//! the daemon's WebSocket server.
//!
//! # Design notes
//!
//! * **Discriminated unions.** TypeScript uses `type: "foo"` and `kind: "bar"`
//!   as discriminants. In Rust these map to `#[serde(tag = "type")]` and
//!   `#[serde(tag = "kind")]` tagged enums.
//! * **Forward compatibility.** The daemon's design explicitly says "frontends
//!   ignore unknown kinds". We mirror that by using `#[serde(other)]` on a
//!   trailing `Unknown` variant and `#[serde(flatten)]` on extensible metadata
//!   maps. Adding new server-side message kinds never breaks an old Rust
//!   client — they deserialize into [`DaemonMessage::Unknown`] and the TUI
//!   logs + skips them.
//! * **Tool state as full replacement.** [`ToolState`] is a tagged enum where
//!   each phase carries its own shape. When a [`SessionMessageDelta`] arrives
//!   with `tool_state_update`, replace the whole [`ToolInfo::state`] — do not
//!   merge fields.
//!
//! # Versioning
//!
//! [`PROTOCOL_VERSION`] is compared against the `protocol_version` field the
//! daemon sends on `auth.ok`. Mismatch is non-fatal (the daemon's additive
//! changes keep old clients working), but the client warns the user so they
//! can upgrade.
