Enum LogicalDeliveryReason 

pub enum LogicalDeliveryReason {
    UnknownAddress,
    ClosedRecipient,
}

One pure communication addressed to a concrete protocol signature.

Protocol identity is not inferred from the payload. Consequently, two protocols with the same address and message types still have distinct delivery types.

struct Queue;
struct Worker;
impl behavior::Protocol for Queue {
    type Addr = behavior::MailAddr;
    type Msg = u8;
}
impl behavior::Protocol for Worker {
    type Addr = behavior::MailAddr;
    type Msg = u8;
}

let worker = behavior::Recipient::<Worker>::global(behavior::MailAddr(1));
let _: behavior::Delivery<Queue> = behavior::Delivery::new(worker, 7);

A destination also fixes its message and address namespaces:

#[derive(Clone, Copy, PartialEq, Eq)]
struct OtherAddr(u64);
impl behavior::Address for OtherAddr {
    type Nonce = u64;
}
struct Worker;
impl behavior::Protocol for Worker {
    type Addr = behavior::MailAddr;
    type Msg = u8;
}
let _ = behavior::Recipient::<Worker>::global(OtherAddr(1));

let worker = behavior::Recipient::<Worker>::global(behavior::MailAddr(1));
let _ = behavior::Delivery::<Worker>::new(worker, "wrong payload");

Exact reason one logical delivery was not accepted.

Trait Implementations

impl Clone for LogicalDeliveryReason

fn clone(&self) -> LogicalDeliveryReason

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LogicalDeliveryReason

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LogicalDeliveryReason

fn eq(&self, other: &LogicalDeliveryReason) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
