Struct DeclaredPluginStore 

pub struct DeclaredPluginStore { /* private fields */ }

In-memory store for declared plugins.

The store is the source of truth for dependency analysis and listing; persistence rides through Persistence and replays the same records through this store on construction.

Implementations

impl DeclaredPluginStore

pub fn new() -> Self

Construct an empty store.

pub fn declare(&self, plugin: DeclaredPlugin) -> Result<(), CustomError>

Declare a new plugin or replace an existing declaration with dependency + cycle validation.

Errors

Returns CustomError::DependencyMissing if any declared dependency is not present in the store. Returns CustomError::DependencyCycle if adding this plugin would introduce a cycle.

pub fn declare_unchecked(&self, plugin: DeclaredPlugin)

Insert / replace without dependency validation. Used by the reactivation path (records from persistence are trusted).

pub fn get(&self, qname: &str) -> Option<DeclaredPlugin>

Look up a declared plugin by qname.

pub fn drop_declared(&self, qname: &str) -> Result<bool, CustomError>

Drop a declared plugin.

Returns true if the plugin existed.

Errors

Returns CustomError::DependencyMissing if the plugin is a dependency of another declared plugin (cascade mode lives at Self::drop_cascade).

pub fn drop_cascade(&self, qname: &str) -> Vec<String>

Drop a declared plugin together with every dependent.

Returns the qnames removed in topological (leaves-first) order.

pub fn replace(&self, plugin: DeclaredPlugin)

Replace an existing record (no validation). Used for shadow-flag updates.

pub fn list(&self) -> Vec<DeclaredPlugin>

List every declared plugin.

Trait Implementations

impl Default for DeclaredPluginStore

fn default() -> DeclaredPluginStore

Returns the “default value” for a type.
