What do you want to do?

I did a quick search and didn't see anything about this.

What do I have to do (if anything) to enable me to INSERT and SELECT structs like MyTable that contain a struct of type Metadata which maps to the created_at and updated_at fields of MyTable's table?

I assume it probably is nontrivial and infeasible, but I feel obligated to ask.

CREATE TABLE my_table (
    id uuid,
    created_at timestamptz,
    updated_at timestamptz.
    foo text,
    bar text
);

struct Metadata {
    created_at: SystemTime,
    updated_at: SystemTime,
}
struct MyTable {
    id: Uuid,
    metadata: Metadata,
    foo: String,
    bar: String,
}

Above is just a simple example, in reality a metadata struct would likely contain many more fields (created_by, updated_by, etc.)

Thanks!
