Trait Requestable

pub trait Requestable {
    type Key: PartialEq + Eq + Hash + Send + Clone;

    // Required methods
    fn req_id(&self) -> Option<Self::Key>;
    fn to(&self) -> Option<Self::Key>;

    // Provided methods
    fn is_request(&self) -> bool { ... }
    fn is_response(&self) -> bool { ... }
}

Responses transmitted over an AsyncConnection can be matched with their request by looking for messages where m1.req_id() == m2.to(). Higher level implementors over AsyncConnection can use any method to generate ID’s of any type that implements Eq + Hash.

Required Associated Types

type Key: PartialEq + Eq + Hash + Send + Clone

Required Methods

fn req_id(&self) -> Option<Self::Key>

Returns the request’s ID if it has one.

fn to(&self) -> Option<Self::Key>

Returns the ID of the request responded to.

Provided Methods

fn is_request(&self) -> bool

If the message has a request ID, it is a request. It is possible for a response to simultaneously be a request.

fn is_response(&self) -> bool

If the message has a response ID, it is a response. It is possible for a response to simultaneously be a request.

Implementors

impl Requestable for ZeroMessage

use zeronet_protocol::message::ZeroMessage;
use zeronet_protocol::requestable::Requestable;

let request = ZeroMessage::request("handshake", 0, "body".to_string());
assert!(request.is_request());
assert!(!request.is_response());

let response = ZeroMessage::response(0, "body".to_string());
assert!(response.is_response());
assert!(!response.is_request());
