Trait for dynamically-typed simulation nodes.

This trait enables type erasure for nodes while preserving essential functionality like shutdown, endpoint access, and type casting.

Required Methods

fn as_any(&self) -> &dyn Any

Returns a reference to this node as Any for downcasting.

fn as_any_mut(&mut self) -> &mut dyn Any

Returns a mutable reference to this node as Any for downcasting.

Provided Methods

fn shutdown(&mut self) -> Pin<Box<dyn Future<Output = Result<()>> + Send + '_>>

Shuts down this node, performing any necessary cleanup.

The default implementation does nothing and returns success.

Errors

Returns an error if shutdown fails.

fn endpoint(&self) -> Option<&Endpoint>

Returns a reference to this node’s endpoint, if any.

The default implementation returns None.

fn round_label(&self, _round: u32) -> Option<String>
