Struct PluginRegistry 

pub struct PluginRegistry<R: PluginRuntime> { /* private fields */ }

Holds all loaded plugins keyed by PluginId.

Thread-safe via RwLock — concurrent reads are cheap; writes (load / unload) take an exclusive lock only while mutating the map.

Implementations

impl<R: PluginRuntime> PluginRegistry<R>

pub fn new(runtime: R) -> Self

Create an empty registry backed by runtime.

pub async fn load( &self, manifest: PluginManifest, plugin: Arc<dyn HomeCorePlugin>, hc: HomeCore, ) -> Result<PluginId, PluginError>

Load a plugin, call its setup hook, and insert it into the registry.

Returns PluginError::AlreadyLoaded if a plugin with the same ID is already registered.

pub async fn unload(&self, id: &PluginId) -> Result<(), PluginError>

Unload a plugin by ID, calling its unload hook first.

Returns PluginError::NotFound if the plugin was not loaded.

pub async fn list(&self) -> Vec<(PluginId, String)>

Return a snapshot of currently loaded plugin IDs and their manifest domains.

pub async fn contains(&self, id: &PluginId) -> bool

Return true if a plugin with this ID is loaded.

pub async fn state_changed( &self, event: &StateChangedEventJson, ) -> Vec<(PluginId, PluginError)>

Dispatch a state change in stable plugin-domain order.

pub async fn shutdown(&self) -> Vec<(PluginId, PluginError)>

Tear down all plugins in reverse domain order. Failures are collected while remaining plugins still receive teardown.
