Struct EstablishedDelivery 

pub struct EstablishedDelivery<P>
where
    P: Protocol,
    P::Addr: EndpointAddress,
{
    pub to: EstablishedRecipient<P>,
    pub message: P::Msg,
}

One pure communication to an exact installed incarnation.

Unlike Delivery, this effect carries the runtime-issued endpoint and requires no address-to-endpoint resolution. Constructing it remains pure; only an explicit crate::InterpretItem implementation for this exact delivery type can perform the communication.

Exact endpoints remain protocol-indexed even when two protocols share an address namespace and message type:

use behavior::{
    Address, EndpointAddress, EstablishedDelivery, EstablishedRecipient,
    Protocol,
};
use core::marker::PhantomData;
#[derive(Clone, Copy, PartialEq, Eq)]
struct RuntimeAddr(u64);
impl Address for RuntimeAddr { type Nonce = u64; }
struct Endpoint<P>(PhantomData<fn() -> P>);
impl<P> Clone for Endpoint<P> {
    fn clone(&self) -> Self { Self(PhantomData) }
}
impl EndpointAddress for RuntimeAddr {
    type Established<P> = Endpoint<P> where P: Protocol<Addr = Self>;
}
struct Queue;
struct Worker;
impl Protocol for Queue { type Addr = RuntimeAddr; type Msg = u8; }
impl Protocol for Worker { type Addr = RuntimeAddr; type Msg = u8; }
let worker = EstablishedRecipient::<Worker>::issued(Endpoint(PhantomData));
let _: EstablishedDelivery<Queue> = EstablishedDelivery::new(worker, 7);
