Implements the Identifiable trait for a given struct. This macro should be called by copy/pasting the definition of the struct into it.

The struct must have a field called id, and the type of that field must be Copy. This macro does not work with tuple structs.

Example

struct User {
    id: i32,
    name: String,
}

Identifiable! {
    #[table_name(users)]
    struct User {
        id: i32,
        name: String,
    }
}
