Struct Envelope 

pub struct Envelope(/* private fields */);

An envelope is a wrapper around message with additional metadata, involved in message passing between actors.

Envelopes aren’t created directly in code, but are produced internally by Context’s methods.

Converting an envelope to a message is usually done by calling the msg! macro, which supports both owned and borrowed usages.
