Queryable with nested structure

[weiwei-lin]

Is there a way to query with nested structure?

#[derive(Queryable)]
struct Foo {
    foo1: i32,
    foo2: i32
}

#[derive(Queryable)]
struct FooBar {
    foo: Foo,
    bar: i32
}

let result = some_table.first::<FooBar>(&conn);

I'm aware that there's QueryableByName, but it seems to require constructing raw query and can't be used with normal queries (e.g. some_table.filter(...).first(&conn)).

You'll need to nest your columns to match the nesting of your structure. For example:

some_table
    .select(((foo1, foo2), bar))
    .first::<FooBar>(&conn)
