Advanced let destructure

We have the following complex data that we want to match against:

// complex_destructure.rsenum Foo {    One, Two, Three}enum Bar(Foo);struct Dummy {    inner: Bar}struct ComplexStruct {    obj: Dummy}fn get_complex_struct() -> ComplexStruct {    ComplexStruct {        obj: Dummy { inner: Bar(Foo::Three) }    }}fn main() {    let a = get_complex_struct();}
