Trait domain_patterns::models::Entity

pub trait Entity<K: Hash + Eq> {
    fn id(&self) -> K;
}

A trait that defines an Entity, which is any object with a unique and globally persistent identity.

The generic type K should match the same type as the internal globally unique id used for the entity. Be careful when choosing what to return here. The result of id() will be used as the primary key for the entity when communicating with a database via a repository.

Example

use domain_patterns::models::Entity;

struct User {
    user_id: String,
    email: String,
    password: String,
}

impl Entity<String> for User {
    fn id(&self) -> String {
        self.user_id.clone()
    }
}

Required methods

fn id(&self) -> K
