Trait Placement 

pub trait Placement: Send + Sync {
    // Required method
    fn route(
        &self,
        to: &Address,
        virtual_actor: bool,
        env: Option<&Envelope>,
    ) -> Route;
}

Decides where virtual actors and stateless workers live in a cluster.

Required Methods

fn route( &self, to: &Address, virtual_actor: bool, env: Option<&Envelope>, ) -> Route

Where the actor at to lives, for delivering env (None when the node asks before activating to, with no message in hand). virtual_actor is true when this node knows to as a virtual actor (its chart type is registered or it has a journal here); the node also asks for stateless workers and for addresses it does not know, which a cluster may host elsewhere. Route::Local for an address the node does not know sends it on to the directory.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
