Implementations

impl PluginSession

pub fn session_id(&self) -> &str

pub fn execution_mode(&self) -> ExecutionMode

pub fn tool_access(&self) -> &SessionToolAccess

pub fn subagent_authority(&self) -> Option<&SubagentSessionAuthority>

pub fn host(&self) -> &PluginHost

pub fn tools(&self) -> Arc<dyn ToolProvider>

pub fn tool_registry(&self) -> Arc<ToolRegistry>

pub fn mode_protocol_driver(&self) -> Option<Arc<dyn ModeProtocolDriverPlugin>>

Plugin-registered protocol driver for this session, if any plugin claimed the singleton slot. When None, callers fall back to lash_sansio::build_mode_preamble (hardcoded Standard/RLM).

pub fn tool_surface( &self, session_id: &str, mode: ExecutionMode, ) -> Arc<ToolSurface>

pub fn tool_catalog(&self, session_id: &str, mode: ExecutionMode) -> Vec<Value>

pub fn resolve_tool_surface( &self, ctx: ToolSurfaceContext, ) -> Result<ToolSurface, PluginError>

pub fn plugin_actions(&self) -> Vec<PluginActionDef>

pub fn monitor_specs(&self) -> &[PluginOwned<MonitorSpec>]

pub fn has_assistant_stream_hooks(&self) -> bool

pub async fn prepare_turn_context( &self, ctx: &TurnTransformContext, input: PreparedContext, ) -> Result<PreparedContext, HistoryError>

Chain registered turn-context transforms, piping each one’s output into the next in priority order.

pub async fn rewrite_history( &self, ctx: &RewriteContext, input: HistoryState, ) -> Result<HistoryState, HistoryError>

Chain registered history rewriters, skipping any that opt out of the current trigger via accepts().

pub async fn collect_prompt_contributions( &self, ctx: PromptHookContext, ) -> Result<Vec<PromptContribution>, PluginError>

pub async fn prepare_turn( &self, request: PrepareTurnRequest, ) -> Result<TurnPreparation, PluginError>

pub async fn after_tool_call( &self, ctx: ToolResultHookContext, ) -> Result<Vec<PluginOwned<PluginDirective>>, PluginError>

pub async fn after_turn( &self, ctx: TurnResultHookContext, ) -> Result<Vec<PluginOwned<PluginDirective>>, PluginError>

pub async fn at_checkpoint( &self, ctx: CheckpointHookContext, ) -> Result<Vec<PluginOwned<PluginDirective>>, PluginError>

pub async fn transform_assistant_stream( &self, session_id: &str, chunk: String, ) -> Result<Vec<PluginOwned<AssistantStreamTransform>>, PluginError>

pub async fn project_tool_result( &self, ctx: ToolResultProjectionContext, ) -> Result<ModelToolReturn, PluginError>

pub async fn emit_runtime_event(&self, event: PluginRuntimeEvent)

pub fn has_runtime_event_hooks(&self) -> bool

pub async fn mutate_session_config( &self, ctx: SessionConfigChangedContext, policy: SessionPolicy, ) -> SessionPolicy

pub fn snapshot(&self) -> Result<PluginSessionSnapshot, PluginError>

pub fn snapshot_is_current( &self, previous: Option<&PluginSessionSnapshot>, ) -> bool

pub fn snapshot_revision_fingerprint(&self) -> u64

pub fn restore( &self, snapshot: &PluginSessionSnapshot, ) -> Result<(), PluginError>

pub fn fork_for_session( &self, session_id: impl Into<String>, execution_mode: ExecutionMode, standard_context_approach: Option<StandardContextApproach>, ) -> Result<Arc<PluginSession>, PluginError>

pub fn fork_for_child_session( &self, session_id: impl Into<String>, parent_session_id: Option<String>, execution_mode: ExecutionMode, standard_context_approach: Option<StandardContextApproach>, authority: SessionAuthorityContext, ) -> Result<Arc<PluginSession>, PluginError>

pub fn fork_for_session_with_tool_surface( &self, session_id: impl Into<String>, execution_mode: ExecutionMode, standard_context_approach: Option<StandardContextApproach>, tool_surface_overlay: ToolSurfaceContribution, ) -> Result<Arc<PluginSession>, PluginError>

pub async fn invoke_plugin_action( &self, name: &str, args: Value, session_id: Option<String>, default_to_current_session: bool, host: Arc<dyn PluginActionHost>, ) -> Result<ToolResult, PluginActionInvokeError>
