Struct Envelope

pub struct Envelope<B> {
    pub src: String,
    pub dest: String,
    pub body: B,
}

A formal structure for any message sent between nodes or clients in a maelstrom orchestrated distributed system.

Fields

src: String

An identifier for the sender of the message.

dest: String

An identifier for the receiver of the message.

body: B

The message payload. Typically, any inbound messages from a client will contain a msg_id field, and outbound messages will contain an in_reply_to field. This is not a hard requirement for inter-node communication, but it is required for inter-client communication. Also, payloads for messages to and from clients should contain a type field, which is used to determine the type of rpc being communicated.

Implementations

impl<B> Envelope<B>

where B: Serialize + DeserializeOwned,

pub fn new(src: &str, dest: &str, body: B) -> Self

Create a new envelope with the given source, destination, and body.

pub fn reply<T>(&self, body: T) -> Envelope<T>

Create a reply to this envelope, with a given body. The source and destination of the envelope will be swapped as this is a reply.
