Struct ActionRegistry 

pub struct ActionRegistry { /* private fields */ }

Registry that maps action names to their handlers.

Thread-safe because every stored handler is Send + Sync.

Implementations

impl ActionRegistry

pub fn new() -> Self

Create an empty registry.

pub fn register(&mut self, handler: Box<dyn ActionHandler>)

Register a handler, keyed by handler.name().

If a handler with the same name already exists it is replaced.

pub fn invoke( &self, entity: &HDict, action: &str, args: &HDict, ) -> Result<HGrid, String>

Dispatch an action invocation to the matching handler.

Returns Err with a descriptive message if no handler is registered for the requested action name.

pub fn list_actions(&self) -> Vec<String>

List all registered action names (in arbitrary order).
