Trait ddd_rs::presentation::Request

pub trait Request: Deserialize<'static> {
    type Response: Serialize;
}

Trait for representing a Request.

Requests are usually commands or queries, and their sole requirement is to have an associated Response type.

• Queries: Return a result and do not change the observable state of the system (are free of side effects).
• Commands: Change the state of a system but do not return a value.

Examples

use ddd_rs::presentation::Request;

#[derive(serde::Deserialize)]
struct MyRequest {
    a: bool,
    b: i32,
    c: String,
}

#[derive(serde::Serialize)]
struct MyResponse {
    foo: String,
    bar: i32,
}

impl Request for MyRequest {
    type Response = MyResponse;
}

Required Associated Types
