帧头，即以 type 字段区分的 JSON 对象。

字段声明顺序即线上顺序，与 Python 模型一致（golden frames 依赖于此）；反序列化时忽略未知字段。

Variants

Hello

Python → Rust：握手首帧，声明协议版本、SDK 版本与已注册的命令。

Fields

protocol: u64

sdk: String

commands: Vec<String>

Ready

Rust → Python：确认握手，Python 收到后执行 ready 钩子。

Fields

protocol: u64

app: AppInfo

Shutdown

Rust → Python：请求退出，timeoutMs 是 Python 取消调用并执行 shutdown 钩子的总预算。

Fields

timeout_ms: u64

Request

Rust → Python：命令调用请求。

Fields

id: u64

Rust 侧分配的调用 id，在单个 crate::bridge::Bridge 内唯一。

cmd: String

channels: BTreeMap<String, u64>

参数名 → channel id。

window: Option<String>

发起调用的 webview 标签。

payload: Inline

Response

Python → Rust：调用成功的结果。

Fields

id: u64

payload: Inline

Error

Python → Rust：调用失败；缺省的 code 按 internal 处理。

Fields

id: u64

code: Option<String>

message: Option<String>

data: Option<Value>

Cancel

Rust → Python：取消调用，reason 为 "client" 或 "timeout"。

Fields

id: u64

reason: String

Event

双向事件。Python → Rust 的事件携带 target，Rust → Python 的事件携带 window。

Fields

event: String

target: Option<String>

目标 webview 标签；缺省时广播。

window: Option<String>

发送事件的 webview 标签。

payload: Inline

ChannelData

Python → Rust：向前端 Channel 推送一条数据。

Fields

channel: u64

payload: Inline

ChannelClose

Python → Rust：关闭 channel，此后该 channel 的数据被丢弃。

Fields

channel: u64
