Struct EvolutionHookHandler 

pub struct EvolutionHookHandler { /* private fields */ }

Hook handler implementing the I008 self-evolution loop. Registered per-Agent in the HookRegistry alongside LoggingHandler.

The same Arc<EvolutionHookHandler> instance is reused across all turns for the Agent’s lifetime; accumulation is stateful via interior mutability (Mutex<TurnObserver> + Mutex<KnowledgeStore>).

Implementations

impl EvolutionHookHandler

pub fn new( store: KnowledgeStore, config: EvolutionConfig, session_id: Option<String>, ) -> Self

Build a handler backed by the given store, config, and session ID.

pub fn open_default( config: EvolutionConfig, session_id: Option<String>, ) -> EvolutionResult<Option<Self>>

Open the default knowledge store at ~/.talos/index.db, creating the .talos directory if it does not exist.

Returns Ok(None) when the home directory cannot be resolved, allowing the caller to continue without evolution rather than aborting the run.

Trait Implementations

impl HookHandler for EvolutionHookHandler

fn name(&self) -> &str

Stable handler name used in logs and tests.
