Struct CommandHandlerStore 

pub struct CommandHandlerStore { /* private fields */ }

Store for command handlers registered by modules.

Modules register their handlers during init() by calling add(). After all modules are initialized, the runner extracts handlers via take_handlers().

Thread Safety

Uses RwLock for interior mutability, allowing modules to register handlers concurrently if needed.

Implementations

impl CommandHandlerStore

pub fn new() -> Self

Create a new empty handler store.

pub fn add(&self, handler: Box<dyn CommandHandler>)

Add a command handler to the store.

Called by modules during init().

Panics

Panics if the lock is poisoned.

pub fn add_arc(&self, handler: Arc<dyn CommandHandler>)

Add an Arc-wrapped command handler to the store.

Panics

Panics if the lock is poisoned.

pub fn take_handlers(&self) -> Vec<Arc<dyn CommandHandler>>

Take all handlers, clearing the store.

Called by runner after all modules are initialized.

Panics

Panics if the lock is poisoned.

pub fn len(&self) -> usize

Get the number of registered handlers.

Panics

Panics if the lock is poisoned.

pub fn is_empty(&self) -> bool

Check if the store is empty.

Panics

Panics if the lock is poisoned.
