Struct PluginStateMap 

pub struct PluginStateMap { /* private fields */ }

Type-keyed map for plugin state with serialization support.

Provides type-safe access keyed by PluginStateKey implementations. Plugins cannot access each other’s state — the type key enforces isolation.

Implementations

impl PluginStateMap

pub fn new() -> Self

Create an empty map.

pub fn register<P>( &mut self, state: P::State, ) -> Result<PluginHandle<P>, &'static str>

where P: PluginStateKey, P::State: Serialize + 'static,

Register plugin state, returning a proof handle.

Errors

Returns the key string if a plugin with the same TypeId is already registered.

pub fn get<P: PluginStateKey>(&self) -> Option<&P::State>

Get an immutable reference to plugin state.

pub fn get_mut<P: PluginStateKey>(&mut self) -> Option<&mut P::State>

Get a mutable reference to plugin state.

pub fn insert<P: PluginStateKey>(&mut self, state: P::State)

where P::State: Serialize + 'static,

Insert or replace plugin state.

pub fn serialize_all(&self) -> Value

Serialize all plugin state to a JSON object keyed by plugin key strings.

Trait Implementations
