Struct Executor 

pub struct Executor { /* private fields */ }

Tool execution engine.

Manages enrichers and dispatches tool calls to providers. Stateless per call — provider is created from AdditionalContext each time.

Implementations

impl Executor

pub fn new() -> Executor

pub fn with_asset_manager(self, mgr: AssetManager) -> Executor

Configure an optional local asset cache for download/delete operations.

pub fn add_enricher(&mut self, enricher: Box<dyn ToolEnricher>)

Register an enricher (provider, pipeline, or custom). Enrichers are applied in registration order.

pub fn list_tools(&self) -> Vec<ToolDefinition>

List available tools with enriched schemas.

1. Starts with base tool definitions
2. Keeps only tools whose category is supported by at least one enricher
3. Applies schema enrichment from enrichers that support each tool’s category

pub async fn execute( &self, tool: &str, args: Value, ctx: &AdditionalContext, ) -> Result<ToolOutput, Error>

Execute a tool with the given arguments and context.

Flow:

1. Pre-execute: enrichers transform args
2. Create provider from context (cheap, stack-allocated)
3. Dispatch tool call to provider method
4. Post-execute: enrichers transform output
5. Return typed ToolOutput

pub async fn execute_direct( &self, tool: &str, args: Value, provider: &dyn Provider, ) -> Result<ToolOutput, Error>

Execute a tool with a pre-created Provider (for MCP server). Enrichers are applied if configured.

pub async fn execute_direct_meeting( &self, tool: &str, args: Value, provider: &dyn MeetingNotesProvider, ) -> Result<ToolOutput, Error>

Execute a meeting tool with a pre-created MeetingNotesProvider.

pub async fn execute_direct_knowledge_base( &self, tool: &str, args: Value, provider: &dyn KnowledgeBaseProvider, ) -> Result<ToolOutput, Error>

Execute a knowledge base tool with a pre-created KnowledgeBaseProvider.

pub async fn execute_direct_messenger( &self, tool: &str, args: Value, provider: &dyn MessengerProvider, ) -> Result<ToolOutput, Error>

Execute a messenger tool with a pre-created MessengerProvider.

pub fn tool_category(tool: &str) -> Option<ToolCategory>

Get the tool category for a tool name, if known.
