}Expand description
Manages a single plugin subprocess instance.
Fields§
§plugin_id: String§manifest: Manifest§state: Arc<RwLock<ProcessState>>§client: Arc<JsonRpcClient>§data_dir: PathBuf§restart_count: u32该插件已重启的次数(0 = 初次启动)。 仅用于观测;权威的重启计数器在 PluginRestartContext 中。
pid: Option<u32>子进程的 PID,用于强制终止(当优雅关闭超时时兜底)。
Implementations§
Source§impl PluginProcess
impl PluginProcess
Sourcepub async fn spawn(
manifest: &Manifest,
plugin_dir: &Path,
data_dir: &Path,
log_dir: &Path,
host_call_handler: Arc<dyn HostCallHandler>,
crash_tx: Sender<String>,
restart_count: u32,
locale: &str,
) -> Result<Self, ProtocolError>
pub async fn spawn( manifest: &Manifest, plugin_dir: &Path, data_dir: &Path, log_dir: &Path, host_call_handler: Arc<dyn HostCallHandler>, crash_tx: Sender<String>, restart_count: u32, locale: &str, ) -> Result<Self, ProtocolError>
Spawn the plugin subprocess, complete the initialize handshake, and start stderr log collection.
crash_tx is a channel sender owned by the PluginHostManager.
When the watchdog detects a crash, it sends the plugin_id on this
channel so the manager can trigger a re-spawn.
启动插件子进程并完成握手与协议版本兼容性校验。
参数较多(进程/目录/回调/计数/locale),按先例 allow too_many_arguments。
Sourcepub async fn discover_components(&self) -> Result<InitResult, ProtocolError>
pub async fn discover_components(&self) -> Result<InitResult, ProtocolError>
Run the post-initialization discovery sequence: plugin/get_components, and for each component: plugin/get_settings_schema, plugin/get_settings, plugin/config_actions. 对 ActionExecutor 组件还会额外调用 plugin/supported_target_types 和 plugin/supported_actions,收集真实的 ResultAction 列表。 插件级元数据由宿主从清单构造,不在本序列。
Sourcepub fn spawn_watchdog(&self) -> JoinHandle<()> ⓘ
pub fn spawn_watchdog(&self) -> JoinHandle<()> ⓘ
生成一个看门狗任务,监控子进程的生命周期。
使用事件驱动的等待(child.wait().await)——没有轮询循环。
当进程退出时:
- 如果状态已经是
Stopped(优雅关闭),静默返回。 - 如果
auto_restart=false,将状态设为Stopped并返回。 - 否则,将
plugin_id发到crash_tx上,通知PluginHostManager重新拉起。管理者(crash_loop)负责追踪重启次数和强制max_restart上限。
任务完成即进程已退出;返回的 JoinHandle 供 shutdown 等待。
