Trait HookExecutor 

pub trait HookExecutor: Send + Sync {
    // Required methods
    fn execute_hook(
        &self,
        hook: &Hook,
        context: &EventContext,
    ) -> Result<HookResult>;
    fn execute_action(
        &self,
        hook: &Hook,
        context: &EventContext,
    ) -> Result<String>;
}

Trait for executing hooks

The HookExecutor is responsible for:

1. Receiving hooks and event context
2. Evaluating hook conditions
3. Executing hook actions (commands, tool calls, AI prompts, chains)
4. Handling timeouts and errors
5. Capturing output and results
6. Providing hook isolation (failures don’t affect other hooks)

Examples

let executor = DefaultHookExecutor::new();
let hook = Hook { ... };
let context = EventContext { ... };
let result = executor.execute_hook(&hook, &context)?;

Required Methods

fn execute_hook( &self, hook: &Hook, context: &EventContext, ) -> Result<HookResult>

Execute a hook with the given context

This method:

1. Evaluates the hook condition (if present)
2. Executes the hook action
3. Captures output and errors
4. Returns a HookResult with status and output

fn execute_action(&self, hook: &Hook, context: &EventContext) -> Result<String>

Execute a hook action

Routes to the appropriate executor based on action type:

• CommandAction: Execute shell command
• ToolCallAction: Call tool with parameters
• AiPromptAction: Send prompt to AI assistant
• ChainAction: Execute hooks in sequence
