Struct SessionHooks 

pub struct SessionHooks { /* private fields */ }

Shared handle captured by agent hook closures.

Lock order (never hold more than one at a time, never across .await):

1. runner (RwLock)
2. system_prompt (RwLock)
3. tools (RwLock)

The agent event pump and public AgentSession methods coordinate through [super::AgentSessionInner]; SessionHooks only exposes runner/prompt/tool snapshots for the pi-agent hook closures.

Implementations

impl SessionHooks

pub fn new(runner: Arc<dyn ExtensionRunner>) -> Self

Create hooks with the given extension runner.

pub fn null() -> Self

Create hooks with a null runner.

pub fn set_runner(&self, runner: Arc<dyn ExtensionRunner>)

Swap the extension runner (reload path).

pub fn runner(&self) -> Arc<dyn ExtensionRunner>

Snapshot the current runner.

pub fn set_base_system_prompt(&self, prompt: String)

Replace the base system prompt.

pub fn set_system_prompt_override(&self, prompt: Option<String>)

Set or clear the per-turn system prompt override.

pub fn system_prompt_snapshot(&self) -> SystemPromptState

Snapshot system-prompt state.

pub fn effective_system_prompt(&self) -> String

Effective system prompt (override or base).

pub fn set_tools(&self, tools: Vec<Arc<dyn AgentTool>>)

Replace the tools snapshot used by prepare_next_turn.

pub fn tools_snapshot(&self) -> Vec<Arc<dyn AgentTool>>

Clone the current tools snapshot.

pub fn before_tool_call_hook(self: &Arc<Self>) -> BeforeToolCall

Build the before_tool_call closure for AgentLoopConfig.

pub fn after_tool_call_hook(self: &Arc<Self>) -> AfterToolCall

Build the after_tool_call closure for AgentLoopConfig.

pub fn prepare_next_turn_hook(self: &Arc<Self>) -> PrepareNextTurn
