Defining our core create API endpoint

For our create endpoint in our core, we only need the following code:

// nanoservices/auth/core/src/api/users/create.rs
use auth_dal::users::schema::{NewUser, User};
use auth_dal::users::transactions::create::SaveOne;
use glue::errors::NanoServiceError;
use serde::Deserialize;
#[derive(Deserialize)]
pub struct CreateUser {
    pub email: String,
    pub password: String
}
pub async fn create<T: SaveOne>(data: CreateUser)
    -> Result<User, NanoServiceError> {
    let user = NewUser::new(data.email, data.password)?;
    let created_item = T::save_one(user).await?;
    Ok(created_item)
}

We can now move onto defining our networking API endpoint.
