Struct Wire 

pub struct Wire<'a> {
    pub from: Did,
    pub me: Did,
    pub payload: &'a [u8],
}

The raw boundary input handed to Protocol::decode: an inbound message’s authenticated sender, this node’s own did, and the opaque payload bytes. decode turns this into the protocol’s typed Event (or rejects it).

from == me marks a self re-injected message (a local command or an effect’s result fed back into the router); any other from is a network message from an authenticated peer (a peer cannot forge from).

Fields

from: Did

Authenticated sender of the message.

me: Did

This node’s own did (so decode can tell self-injection from a peer).

payload: &'a [u8]

Opaque payload bytes; the protocol’s own codec decides how to read them.
