第三方插件子进程的顶层管理器。
Fields§
§processes: Arc<DashMap<String, Arc<PluginProcess>>>已加载插件的子进程映射。
plugins: Arc<DashMap<String, PluginRegistration>>已加载插件的组件注册包(含 DataSource / Executor / Plugin 适配器)。
data_dir_root: PathBuf插件数据的根目录。
log_dir_root: PathBuf插件 stderr 日志的根目录。
Implementations§
Source§impl PluginHostManager
impl PluginHostManager
pub fn new( plugins_dir: PathBuf, data_dir_root: PathBuf, log_dir_root: PathBuf, ) -> Arc<Self> ⓘ
Sourcepub fn set_builtin_component_ids(&self, ids: HashSet<String>)
pub fn set_builtin_component_ids(&self, ids: HashSet<String>)
注入内置组件 id 集合(冲突预检数据源)。
由 src-tauri 在内置组件注册完毕后调用一次;此后内置组件集合 启动期稳定,不再更新。预检据此识别「与内置组件撞 id」。
Sourcepub async fn load(
&self,
plugin_dir: &Path,
host_call_handler: Arc<dyn HostCallHandler>,
on_restart: RestartCallback,
on_crash: CrashCallback,
restart_count: u32,
locale: &str,
) -> Result<PluginRegistration, PluginLoadError>
pub async fn load( &self, plugin_dir: &Path, host_call_handler: Arc<dyn HostCallHandler>, on_restart: RestartCallback, on_crash: CrashCallback, restart_count: u32, locale: &str, ) -> Result<PluginRegistration, PluginLoadError>
从包含 manifest.toml 的目录加载一个插件。
on_restart 存入重启上下文,崩溃重启成功后被调用,
供调用方(src-tauri)重新注册新适配器。
on_crash 在崩溃检测到的那一刻(任何重启尝试之前)以旧注册包调用,
供调用方解注册 CM/SR 中的过期组件。
restart_count 为已发生的重启次数(初次加载传 0),用于延续崩溃恢复计数。
locale 为宿主当前界面语言,随 initialize 握手下发插件进程。
Sourcepub fn plugins_dir(&self) -> &Path
pub fn plugins_dir(&self) -> &Path
返回插件安装目录(显式存储,非派生)。
Sourcepub async fn unload(&self, plugin_id: &str) -> Result<(), PluginLoadError>
pub async fn unload(&self, plugin_id: &str) -> Result<(), PluginLoadError>
卸载插件:关闭子进程、移除全部登记并删除诊断日志(含轮转 .log.1)。 与 teardown(加载失败清理)的区别:teardown 保留日志供故障溯源。
Sourcepub fn update_locale(&self, plugin_id: &str, locale: &str)
pub fn update_locale(&self, plugin_id: &str, locale: &str)
更新插件重启上下文中的语言快照。
宿主在崩溃回调中调用(崩溃时刻取最新语言),保证崩溃重启的 initialize 握手携带最新 locale,而非首次加载时的快照。 插件不存在(正常卸载等)时静默。
Sourcepub fn list_plugin_info(
&self,
enabled_fn: impl Fn(&PluginRegistration) -> bool,
) -> Vec<InstalledPluginInfo>
pub fn list_plugin_info( &self, enabled_fn: impl Fn(&PluginRegistration) -> bool, ) -> Vec<InstalledPluginInfo>
为全部已加载适配器构造 InstalledPluginInfo。
enabled_fn 按适配器调用以确定 enabled 字段;
调用方传入查询 ConfigManager::is_enabled 的闭包。
Sourcepub fn get_plugin_info(
&self,
plugin_id: &str,
enabled_fn: impl Fn(&PluginRegistration) -> bool,
) -> Option<InstalledPluginInfo>
pub fn get_plugin_info( &self, plugin_id: &str, enabled_fn: impl Fn(&PluginRegistration) -> bool, ) -> Option<InstalledPluginInfo>
单个插件的运行时信息(按 id 直查 hm.plugins,不遍历全量列表)。
与 list_plugin_info 共用同一构造逻辑(build_plugin_info)。
