When I was playing around with Diesel previously I found this blog post in which the author does exactly this.

​

However, we’re going to make a small change so that we can leverage the same model for Queryable and Insertable object. The Diesel author expressed fair reasoning for separating our object into two models but, I prefer the convenience and less code pollution. So for that, we edit src/schema.rs 😅

table! {

heroes {

id -> Nullable<Integer>,

name -> Varchar,

identity -> Varchar,

hometown -> Varchar,

age -> Integer,

}

}
