create_vector generates the wrong type

[MarkSwanson]

create_vector() returns a type that can not be used: Offset<Vector<Offsettest::new_request_v2::Pair>>

I can't use it because when I use the generated add_*() method I get:

 //expected `Offset<Vector<Offset<test::new_request_v2::Pair>, &new_request_v2::Pair>>`,
 //found `Offset<Vector<Offset<test::new_request_v2::Pair>>>`

So Vector<> needs to be constructed with T, I. create_vector() needs a different return type?

This is the generated add_*() fn:

pub fn add_x(&mut self, x: fb::Offsetfb::Vector<fb::Offset<Pair, &Pair>>)

I tried to create a new create_vector() but it required lifetimes, and these lifetimes trickled down into problems with Indirect impls etc. so I don't think that's what we want.

Suggestions?
Thanks!

Workaround in 2 steps:

1. create the Vector manually:

   fbb.not_nested();
    fbb.start_vector(headers_slice.len(), mem::size_of::<Offset<Pair>>());
    for &elem in headers_slice.iter().rev() {
        fbb.push_offset(elem);
        //fbb.push_scalar(elem);
    }

2: force the compiler to create the type you want

let headers: Offset<Vector<Offset<new_request_v2::Pair>, &new_request_v2::Pair>> = Offset::new(fbb.end_vector(headers_slice.len()));

Then, just use your headers normally:

builder.add_headers(headers);

NOTE: Pair is a simple flatbuffer Table in my new_request_v2 schema:

table Pair {
    name:string;
    value:string;
}

Also, 'headers' is just how I use the Pair in my root flatbuffer schema.

It would be nice if the Rust flatbuffers library could provide a create_vector_of_tables() helper fn to do this.

Thanks!
