Implementations§

Source§

impl PluginHostManager

Source

pub fn scan_dirs(&self) -> Vec<PathBuf>

枚举包含 manifest.toml 的插件目录(不解析清单)。 返回:目录列表;安装根目录不存在时为空。

仅用于启动期加载(load_all_third_party);列表/详情一律读内存快照。

Source

pub fn installed_snapshot(&self) -> Vec<Arc<InstalledPlugin>>

已安装插件的内存快照(Arc 克隆,无磁盘 IO)。

Source

pub fn refresh_installed(&self)

立即重扫安装目录并替换快照。

安装/卸载/重载链路在动作完成后调用,保证紧随其后的 IPC 读到新事实; 监听线程同样只调用本方法,刷新逻辑唯一。

Source

pub fn installed(&self, plugin_id: &str) -> Option<Arc<InstalledPlugin>>

按清单 id 定位安装记录:已加载取注册包快照,否则读内存安装快照。 参数:plugin_id - 插件 id。 返回:安装记录;未安装(或快照尚未刷新到)返回 None。

Source

pub fn start_installed_watcher(&self) -> Result<()>

启动插件目录监听:目录变更后异步重扫安装快照。

幂等:已启动直接返回 Ok。最终一致(事件合并窗口约 300ms),覆盖用户手动 拷贝/删除插件目录的场景;监听失败只降级为「只在动作后刷新」,不阻断启动。 返回:启动成功 Ok(()),创建目录或监听失败返回错误。

Source

pub fn to_info( &self, installed: &InstalledPlugin, is_component_enabled: impl Fn(&str) -> bool, ) -> PluginInfo

安装记录 → 展示条目:已加载取运行时注册,未加载呈现 error 态。 参数:installed - 安装记录;is_component_enabled - 组件启用态谓词(由调用方提供)。 返回:IPC 展示条目(未加载时组件为空、enabled 为 false)。

Source§

impl PluginHostManager

Source

pub fn new( plugins_dir: PathBuf, data_dir_root: PathBuf, log_dir_root: PathBuf, ) -> Arc<Self> ⓘ

Source

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」。

Source

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。

Source

pub fn plugins_dir(&self) -> &Path

返回插件安装目录(显式存储,非派生)。

Source

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。

Source

pub async fn shutdown_all(&self)

关闭全部已加载插件的子进程(应用退出路径)。

调用约定:进入本方法前,调用方必须已对每个插件执行 Plugin::on_shutdown (应用退出路径由 src-tauri 遍历插件注册表统一完成)。本方法只负责关闭进程, 不再重复发送退出钩子。 与 unload 的区别:不删除诊断日志,只关闭进程并清空登记。 与 load/teardown 共用 load_lock,避免与并发的加载/卸载交错; 各进程并发关闭,整体耗时上限为单插件的退出等待预算。

Source

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。

Source

pub fn get_plugin_info( &self, plugin_id: &str, is_component_enabled: impl Fn(&str) -> bool, ) -> Option<PluginInfo>

单个插件的运行时条目(按 id 直查,不遍历全量列表)。

返回 None 表示该插件当前未加载;调用方据此区分运行态与「已安装未加载」。 启用态 = 插件自身 Plugin 组件的启用态(路由只认插件 id)。
