Struct HookRegistry 

pub struct HookRegistry { /* private fields */ }

A registry of hooks that dispatches events to all registered hooks in order.

Hooks are stored as Arc<dyn Hook> and dispatched sequentially. If any hook returns HookAction::Skip or HookAction::Error from a PreToolCall event, the first non-Continue action is returned and remaining hooks are not called for that event.

Implementations

impl HookRegistry

pub fn new() -> Self

Create an empty hook registry.

pub fn register(&mut self, hook: Arc<dyn Hook>)

Register a hook. Hooks fire in registration order.

pub fn dispatch(&self, event: HookEvent<'_>) -> HookAction

Dispatch an event to all registered hooks.

Returns the first non-Continue action, or Continue if all hooks agree. For non-PreToolCall events, Skip and Error are converted to Continue.

pub fn is_empty(&self) -> bool

Returns true if no hooks are registered.

pub fn len(&self) -> usize

Returns the number of registered hooks.
